var object = $("#lstValue_chosen").find('.chosen-choices').find('input[type="text"]')[0];
var _KeyCode = event.which || event.keyCode;
if (_KeyCode != 37 && _KeyCode != 38 && _KeyCode != 39 && _KeyCode != 40) { 

    if (object.value != "") {
        var SelectedObjvalue = object.value;
        if (SelectedObjvalue.length > 0) {
            var obj = { value: SelectedObjvalue };
            var SelectedListValue = $('#lstValue').val();
            var Uniqueid = $('#uniqueid').val();

            $.ajax({
                url: '/Admin/GetUserListBox?SelectedValue=' + SelectedListValue + '&Uniqueid=' + Uniqueid,
                data: { value: SelectedObjvalue },
                type: 'GET',
                async: false,
                success: function (response) {
                    if (response.length > 0) {
                        $('#lstValue').html('');
                        var options = '';                            
                        $.each(response, function (i, obj) {
                            options += '' + obj.Text + '';
                        });
                        $('#lstValue').append(options);
                        $('#lstValue').val(SelectedListValue);
                        $('#lstValue').trigger("chosen:updated");
                        object.value = SelectedObjvalue;
                    }
                },
                error: function (xhr, ajaxOptions, thrownError) {
                    //jAlert("Error. Please, check the data.", " Deactivate User");
                    alert(error.StatusText);
                }
            });
        }
    }
}
