title: Ext RowEditor.js does not fire 'afteredit' event
body: <p>I have a Ext grid with RowEditor plugin. I have the following code to add 'afteredit' event to the roweditor object.</p>
  
  <pre><code>store.on('update',function(){
      });
  
      editor.on("afteredit",function(roweditor,changes,record,index){
  
          $.ajax({
              url: $("#web").val() + "/registration/client/address-save"
              ,type: 'post'
              ,data: record.json
              ,dataType: 'json'
              ,success: function(data){
                  if(data.success == true){
                      alert("Update Successfully");
                  }
              }
          });
      });
  </code></pre>
  
  <p>when I click a row and edit a value, sometimes the grid fires 'afteredit' event, but sometimes it doesn't.</p>
  
  <p>Do I have a problem with my code above?</p>
