Question

jend와 kendo 모바일 listview를 바인딩하려고합니다. listview 데이터를 올바르게 표시하지만 필터를하면 다음 오류가 발생합니다.

Uncaught TypeError: Object [object Object] has no method 'toLowerCase'

<div data-role="view" data-init="mobileListViewPullToRefresh" data-title="Pull to refresh" id="typelist"> 
     <header data-role="header"> 
      <div data-role="navbar"> 
       <span data-role="view-title"></span> 
       <a data-align="left" data-icon="add" data-role="button" data-rel="modalview" href="#modalview-add"></a> 

      </div> 
     </header> 

     <ul id="pull-to-refresh-listview" data-role="listview" data-style="inset"></ul> 
    </div> 

    <div data-role="modalview" id="modalview-add" style="width: 95%; height: 12em;"> 
     <div data-role="header"> 
      <div data-role="navbar">

    <script type="text/javascript"> 
     $(document).ready(function() {

      function loadtypes() { 

       $("#pull-to-refresh-listview").empty(); 
       var murl = "/Home/getTypes/"; 
       $.ajax({ 
        url: murl, 
        cache: false,

        contentType: "application/json; charset=utf-8", 
        dataType: 'json',

         var dataSource = new kendo.data.DataSource({ data:data }); 
         $("#pull-to-refresh-listview").kendoMobileListView({ 
          dataSource: dataSource, 
          template: "#: type_name #", 
          filterable: true, 
          virtualViewSize: 50 // needed setting, since local data virtualization does not use paging 
         }); 

         return dataSource; 

        }, 
        error: function (reponse) { 
         return '{"error":"Error"}'; 
        } 
       }); 
      } 

     }); 
    </script> 

JSON :

[{"id":0,"type_name":"Beverages"},{"id":0,"type_name":"Meat"},{"id":0,"type_name":"test"},{"id":0,"type_name":"test2"},{"id":0,"type_name":"test3"},{"id":0,"type_name":"test4"},{"id":0,"type_name":"test5"},{"id":0,"type_name":"test7"},{"id":0,"type_name":"test8"},{"id":0,"type_name":"type6"}]
