title: Kendo Grid - Add New Item after sorting issues
body: <p>I am using  Kendo UI v2014.1.528</p>
  
  <p>Binding data in Kendo Grid like below</p>
  
  <pre><code> $("#list485").kendoGrid({
                  dataSource: dataSource,
                  sortable: true,
                  columns: [
                      //Column List
                  ]
                 );
  </code></pre>
  
  <p>It gives me a grid with <strong>"Sort"</strong> and <strong>"Add New Record"</strong> feature.</p>
  
  <p>If i click on "Add New Record" button, it adds an <strong>empty record in the first row of the grid</strong>. This is fine.</p>
  
  <p>But if i sort the grid on any column and then click on "Add New Record" button, <strong>the empty row for new record gets added somewhere in between the existing rows</strong>.</p>
  
  <p>Can someone help me understand and fix this issue?</p>
