title: Kendo grid/datasource/grouping
body: <p>Ok I have a grid setup binding to local data</p>
  
  <p>Here it is based on the examples in the kendo demos

  <p>I'm having problems when rows are deleted. They appear to be deleted but then the original rows re-appear when columns are grouped.</p>
  
  <p>Grouping works when 1 row is left - delete both rows (they disappear) group by a column and the original 2 come back!</p>
  
  <p>I thought that the datasource automatically updated based on the destroy events. Am I missing something that will update the original data array from the datasource?</p>
