Are you trying to add values to the dataGrid Column row? Or to the DataGrid's dataProvider? If you're updating the dataProvider, then the DataGrid won't necesarilly automatically update the itemRenderer, because the dataChange event won't fire automatically. In your dataProvider is a collection class, you can use the itemUpdated() method.

dataProvider.itemUpdateD(myUpdatedItem);

Which will trigger the DataGrid to update. You can also use the refresh method:

dataProvider.refresh();

But, considering the lack of code you provided, I'm just guessing.
