title: Kendo Grid: Canceling edit deletes new row
body: <p>Here is a <a href="http://plnkr.co/edit/X4ei0zPYiZ1H8AiCTy8B?p=preview" rel="noreferrer">demo</a> to for the behavior I am experiencing.</p>
  
  <p>If you edit the existing row with id 1, change the text to something else and then press the cancel button, the row is reverted correctly to its previous state.</p>
  
  <p>In order to reproduce my problem you need to:</p>
  
  <ul>
  <li>Add a new row</li>
  <li>Press the update button to save it.</li>
  <li>Select the row again and press the update button.</li>
  <li>Press the cancel button</li>
  <li>The row disappears!</li>
  </ul>
  
  <p>Even though there are similar questions on this problem, I have yet to find a satisfactory answer.</p>
  
  <p>Some people say that I need to define an id. As you can see from my demo, this does not make any difference, the new row has an id and it still disappears.</p>
  
  <p>There are some suggestions when you are using a remote datasource, but this does not work in my case, I need to use local data.</p>
  
  <p>Finally, there is <a href="https://stackoverflow.com/a/18649679/89435">this</a> answer. While it does prevent the new row from disappearing, Canceling the row does not revert the data to its old state, it only closes the editor and the data are as they where after the edit.</p>
