Chosen Jquery array to php codeigniter controller via AJAX post

I am working on a multiple selection using chosen jquery. the values are already stored on an array. But im having problem with the AJAX post to send the values of the array to the controller. I already looked over the internet for solutions, spent so much time on reading articles here but non of it solves my problem. Please help.

Here is my code:

 $(document).ready(function(){ 
    var status = [];
    var method = $(this).attr('data-method');    // confirm(status);
    var config = {
      '.chosen-select'           : {},
      '.chosen-select-deselect'  : {allow_single_deselect:true},
      '.chosen-select-no-single' : {disable_search_threshold:10},
      '.chosen-select-no-results': {no_results_text:'Oops, nothing found!'},
      '.chosen-select-width'     : {width:"95%"}
    }
    for (var selector in config) {
      $(selector).chosen(config[selector]);
    }
        $("#test").chosen().change(function(e, params){

      console.clear()

      $("#test :selected").each(function(i,selected)
      {

             status[i] = $.trim($(selected).text());
            // status.push($(this).val());
      })

    console.log(status);     
    var new_var = JSON.stringify(status);


    // $('.statusArray').click(function(e){

      $.ajax({
        type: "POST",
        url: "<?php echo site_url('request/buyer') ?>",
        data: { data: new_var }
      }).done(function(data) {
        console.log(data);
        alert( "Data Send:");
      }).fail(function() {
        alert( "Data Not Send" );
      });
      e.preventDefault();



    enter code here
    // });


     });    });
