GroupGridView does not reflect changes in a section

[hoeverma]

Hi! We are currently evaluating this widget, as we would need exactly this functionality. So far, everything is ok, and we thank you very much for this great work!
There is one problem we have, and I am not sure if we use the component in a wrong way, or if it is a bug: Our datasource is structured very simple, just like yours in the example. We can tap on one of the items in a section, and then delete this item in the database. But the item does not disappear from its section on the screen. Although reloading the complete datasource again form database, followed by a call to setState does not help. Nevertheless, the datasource is correct: The deleted item is no linger present. Could you please give a hint what we could do?

Thank you for your help!
