                source: function () {
                    $.ajax({
                        type: "POST",
                        url: "../BUS/WebService.asmx/LIST_BU",
                        contentType: "application/json; charset=utf-8",
                        dataType: "json",
                        //beforeSend: function () { $('ul.cb_bu_info').empty(); },
                        success: function (data) {
                            $("#cb_bu_info").html('');
                            $.each($.parseJSON(data.d), function (idx, obj) {
                                $("#cb_bu_info").append('<option value="' + obj.BU_ID + '">' + obj.BU_NAME + '</option>');
