title: Kendo Grid dataItem selection is not working in IE
body: <p>I have two kendo grids in a page, I am trying to transfer some items from one grid to another on button click . my code is working perfectly in Chrome but not in IE.</p>
  
  <pre><code>$('#btn_move_1_2').on('click', function(){
      var grid1 = $('#grid1').data('kendoGrid');
      var grid2 = $('#grid2').data('kendoGrid');
      grid1.select().each(function(key , value){
  
          var currItem = grid1.dataItem(value);
          grid1.dataSource.remove(currItem);
          //on second iteration gets error- Unable to get property 'uid' of undefined or null reference
          grid2.dataSource.add(currItem);
      });
      grid1.select().each(function(){ grid1.removeRow($(this)); });
      grid2.refresh();
  });
  </code></pre>
  
  <p>single selection will work fine. on multiple selection it broke in second iteration with error "Unable to get property 'uid' of undefined or null reference"</p>
  
  <p>I created a sample snippet to show the error <a href="http://dojo.telerik.com/@jomet/oVICI" rel="nofollow">http://dojo.telerik.com/@jomet/oVICI</a></p>
