title: kendo grid date format datasource
body: <p>I have a kendo grid with a date column. In order to format the date, I'm using:
  format: <code>{0: dd/MM/yyyy }</code>. </p>
  
  <p>All is well, until I try updating the data source of the grid:</p>
  
  <pre><code>                    chargesDS.data(ko.toJS(newValue));
                      chargesDS.sync();
                      chargesGrid.refresh();
  </code></pre>
  
  <p>the .data() call (first line) breaks the date column, causing the format to go back to some default format. </p>
  
  <p>Is there a way to refresh the grid so that the dates are displayed properly again?</p>
