\qmlsignal QtQml.Models::DelegateModelGroup::changed(array removed, array inserted)
This signal is emitted when items have been removed from or inserted into the group.
Each object in the removed and inserted arrays has two values; the index of the first item inserted or removed and a count of the number of consecutive items inserted or removed.
Each index is adjusted for previous changes with all removed items preceding any inserted items.
