title: ngGridEventEndCellEdit and row index
body: <p>on ngGridEventEndCellEdit (angular grid) I need to know the index of the row edited: I saw that this event returns a parameter with many data but I don't have found it! :-(</p>
  
  <pre><code>$scope.$on('ngGridEventEndCellEdit', function (data) {
      console.log(data);
  });
  </code></pre>
