script for creating dynamic input box

$(document).ready(function() {

  var max_fields      = 3;                      //maximum input boxes allowed
  var wrapper         = $(".input_fields_wrap");    //Fields wrapper
  var add_button      = $(".add_field_button");     //Add button ID
  var x = 1;                                         //initlal text box count
  $(add_button).click(function(e){              //on add input button click
    e.preventDefault();
    if(x < max_fields){                         //max input box allowed
        x++;                                    //text box increment
        $(wrapper).append('<div class="detailroweno"><span class="code"><input type="text" name="job_title_id[]"/></span></div>'); //add input box
