jQuery Plugin Function Returning Undefined For The Value

I created a jQuery plugin to do various things with cookies. The trouble I am having is the function I created to read the cookie and return the value. No matter what I do, when I call the function as so from the main page

test = $.cookie({
        action:'get', 
        cookie_name:LOGIN_COOKIE_NAME
    });

the return is ALWAYS undefined. Console output is as follows:

Value found is => 10
Returned => undefined

I'm at my wit's end trying to figure out what's going on here. I've tried everything I know to do and spent literally hours Googling this with no solution. Below is the code in my jQuery plugin:

// Get the value of the sought after cookie

    function get_cookie(){
      var value = '';
      // Get the name to search for
      var name = settings.cookie_name;
      
      // Divide the cookie string into an array
      var ca = document.cookie.split(';');
      
      // Loop through each element in the main array we just created
      match_found = false;
      for(var i=0; i<ca.length; i++){
          // Clear the whitespace from the ends to prevent mismatches and split each > element into the cookie name and value
          var temp = ca[i].trim().split('=');
          
          // Now check to see if this is the cookie we are looking for
          if(temp[0] == name && !match_found){
              match_found = true;
              // If it is, then return the cookie's value
              cookie_value = temp[1]+'';
              if(settings.action != 'check'){
                  value = cookie_value;
              }else{
                  value = true;
              }
          }
      }
      if(!match_found && settings.action == 'check'){
          return false;
      }else if(!match_found && settings.action != 'check'){
          return 'dooby';
      }else{
          console.log('Value found is => '+value);
          return value;
      }
    }

Does anyone have any insight into what's causing this and how it can be corrected?

Here is the entire code of my jQuery plugin

(function($){
$.cookie = function(options) {
    
    // Default Settings
    var settings = $.extend({
        action : 'check', // create or delete
        cookie_name : 'cookie',
        cookie_value : 'default',
        expiration : 'Sun, 31 Dec 2017 12:00:00 GMT',
        path : '/'
    }, options);
    
    switch(settings.action){
        case "create":
            create_cookie();
            break;
        case "delete":
            delete_cookie();
            break;
        case "check":
            return check_for_cookie();
            break;
        case "get":
            get_cookie();
            break;
        default:
            get_cookie();
            break;
    }
    
    
    
    
    
    
    // Create the cookie
    function create_cookie(){
        try{
            document.cookie = settings.cookie_name+"="+settings.cookie_value+"; expires="+settings.expiration+"; path="+settings.path;
            console.log("Cookie Created");
        }catch(e){
            console.log(e);
        }
    }
    
    
    // Delete said cookie
    function delete_cookie(){
        document.cookie = settings.cookie_name+"="+settings.cookie_value+"; expires=Sun, 29 Dec 2013 12:00:00 GMT; path="+settings.path;
    }
    
    
    // Get the value of the sought after cookie
    function get_cookie(){
        var value = '';
        // Get the name to search for
        var name = settings.cookie_name;
        
        // Divide the cookie string into an array
        var ca = document.cookie.split(';');
        
        // Loop through each element in the main array we just created
        match_found = false;
        for(var i=0; i<ca.length; i++){
            // Clear the whitespace from the ends to prevent mismatches and split each element into the cookie name and value
            var temp = ca[i].trim().split('=');
            
            // Now check to see if this is the cookie we are looking for
            if(temp[0] == name && !match_found){
                match_found = true;
                // If it is, then return the cookie's value
                cookie_value = temp[1]+'';
                if(settings.action != 'check'){
                    value = cookie_value;
                }else{
                    value = true;
                }
            }
        }
        if(!match_found && settings.action == 'check'){
            return false;
        }else if(!match_found && settings.action != 'check'){
            return 'dooby';
        }else{
            console.log('Value found is => '+value);
            return value;
        }
    }
    
    
    // Check to see if said cookie exists
    function check_for_cookie(){
        var is_set = get_cookie(settings.cookie_name);
        if(is_set){
            return true;
        }else{
            return false;
        }
    }
};
}(jQuery));

SOLUTION:

Thanks to OJay below for the keen eye and the solution to this. Scroll down and give him some upvotes.

The call to get_cookie() in the main switch statement that handles what action to take was not returning anything. So following OJay 's solution it now works by looking like this:

case "get":
    return get_cookie();
    break;
