title: How I can set and get template columns value/text in kendo Grid
body: <p>Consider I have a kendo grid like following <br/>
  <a href="http://jsbin.com/uxumab/1/" rel="nofollow">http://jsbin.com/uxumab/1/</a></p>
  
  <p>It has ItemId, Qty, Price and Total(template) column.
  I want to make Qty column editable and want to change total column value with the change of Qty column.
  Finally I want to retrieve all the values with new changes using iteration through grid.</p>
