title: Event called when sorting data in kendo grid
body: <p>I have the sample codes as follows:</p>
  
  <pre><code>  $(document).ready(function () {
      $("#grid").kendoGrid({
          dataSource: getData(),
          height: 550,
          sortable: true,
          pageable: true,
          columns: [{
              field: "ContactName",
              title: "Contact Name",
              width: 200
          }, {
              field: "ContactTitle",
              title: "Contact Title"
          }, {
              field: "CompanyName",
              title: "Company Name"
          }]
      });
         function whenSorting(){
             //// DO SOMETIME......
         }
       });
  </code></pre>
  
  <p>Now what I want is when I do sorting of any field the function "whenSorting" will be called.  How to do that?</p>
