OnChange / AfterEdit event for EditorGrid with checkbox column

[egotec]

Hello.

I have a EditorGrid with a Checkbox column:

CellEditor checkBoxEditor = new CellEditor(new CheckBox());
[...]
gridEmployees = new EditorGrid<ModelData>(new ListStore<ModelData>(), new ColumnModel(configs_3));

Now, I'd like to be notified when a row was edited.

gridEmployees.addListener(Events.AfterEdit, changeListener);

But the event isn't coming when I check the checkbox. When I use a SimpleComboBox instead of the CheckBox, the event is coming when I change the selection. But I need the checkbox...

Thanks for your help,
Jonas.
