you can put this function in your code:

ajaxService = (function () {
var ajaxGetJson = function (callback,  isAsyncCall) {

    //by default is an asyncrounous call
    isAsync = (typeof isAsyncCall === "undefined") ? true : isAsyncCall;

    $.ajax({
        url: "http://yourserviceorserversideapphere",
        type: "GET",
        data: request,
        dataType: "json",
        contentType: "application/json; charset=utf-8",
        async: isAsync,
        success: function (result, statusMsg, status) //3 parameters always come from ajax
        {
            callback(result, statusMsg, status, request);
        },
        error: function (result, statusMsg, status) //3 parameters always come from ajax
        {
            ServiceFailed(result, statusMsg, status, getSvcUrl(service, method));
        } // When Service call fails
    });
};

then in your del button:

$('.del').click(function(){
    ajaxService.ajaxGetJson(successAjaxCall, true);
}

and then you will have the function that you pass in your callback (successAjaxCall) to do what the .del button is doing in your code.

function successAjaxCall(result, statusMsg, status) {

   //you can use the result object to do anything you want here
