Kendo UI Grid 获取当前元素 javascript 的 ID

我正在使用Kendo UI apsnet，我在第三列中有一个带有自动组件作为模板的Gird，我想使用javascript函数"onAutoCompleteX"发送数据，在这个函数中，我想获取活动自动完成的id，以将文本作为参数发送到操作"GetArticle"，但我的问题是如何获取此id，尝试了许多方法总是得到"未定义"或错误

@using KendoUIMvcApplication2.Areas.Gescom.Models.Achat

<style>
    .k-widget .templateCell
    {
        overflow: visible;
    }
</style>
 <script> 
    function initMenus(e) {
        $(".templateCell").each(function () {
            eval($(this).children("script").last().html());
        });
    }
    function onAutoCompleteSelectX(e) {
        var dataItem = this.dataItem(e.item.index());
        var url = '@Url.Action("GetArticle", "Fiche")';
        $.ajax({
            url: url,
            data: { code: dataItem.Code }, //parameters go here in object literal form
            type: 'GET',
            datatype: 'json',
            success: function (data) {
                if (data == null)
                    document.getElementById('labelx').innerHTML = "null";
                else
                    document.getElementById('labelx').innerHTML = data.Code;
            },
            error: function () {
                document.getElementById('labelx').innerHTML = "error";
            }
        });
    }

     function onAutoCompleteX() {
         var currentId = $(this).attr('id');
         //var currentId = $(this).id;
         //document.getElementById('labelx').innerHTML = $(this).className; //$obj.attr('id');
         return {
             text: document.getElementById(currentId).value
             //text: $("#id_of_another_autocomplete").val() works fine when i set static id manually
         };
     }
