<script src="theme/js/jQuery-2.1.3.min.js"></script>
    <link href="theme/chosen_v1.4.2/chosen.css" rel="stylesheet" />
    <script src="theme/chosen_v1.4.2/chosen.jquery.js"></script>

       $(document).ready(function () {
           $(".cb_bu_info").chosen({
               width: "95%",
               source: function (data) {
                   $.ajax({
                       type: "POST",
                       url: "../BUS/WebService.asmx/LIST_BU",

                       dataType: "json",
                       success: function (data) {
                           $("#cb_info").html('');
                           //$.each($.parseJSON(data.d), function (idx, obj) {
                           $.each(data, function (idx, obj) {
                               $("#cb_info").append('<option value="' + obj.BU_ID + '">' + obj.BU_NAME + '</option>');
                           });  
                          //$("#cb_info").trigger("liszt:updated");
                       },
                       error: function (data) {
                           console.log(data.d);
                       }
                   });
               }
           });

           $("#cb_info").trigger("liszt:updated");
        });
    </script>

<select id="cb_info" class="cb_bu_info"></select>

The data form ajax as

[{"BU_ID":"B01","BU_NAME":"Agro Feed","BU_DES":"Agro Feed","EDIT_DATE":"2015-05-05T00:00:00","EDIT_BY":"","FLAG":false},{"BU_ID":"B02","BU_NAME":"Agro Farm","BU_DES":"Agro Farm","EDIT_DATE":"2015-05-05T00:00:00","EDIT_BY":"","FLAG":false}]

Well , it's look ok , but when i run it , result not show in select option, see browser dev tool , I've not seen error. Anything is ok.What's the problem happen in here? Notes: only use Chosen Jquery

After checking out the Chosen docs, there seems to not be a "source" option. What you need to do is first run your Ajax call, then fill your select options. Once the select is all filled, then run Chosen on that select element.

I would use the following JS code:

var url = "../BUS/WebService.asmx/LIST_BU";
$.getJSON(url, function(json){
    var $select_elem = $("#cb_info");
    $select_elem.empty();
    $.each(json, function (idx, obj) {
        $select_elem.append('<option value="' + obj.BU_ID + '">' + obj.BU_NAME + '</option>');
    });
    $select_elem.chosen({ width: "95%" });
})
