ListView does not notify count changes properly

If you create a binding to ListView.count the value is not updated correctly.

If model is set to ListView before the delegate (which seems to be the normal case) ListView returns 0 (zero) for the count. Only after the delegate is set count returns the correct value. Unfortunately countChanged signal seems to be missing from QDeclarativeListView::setDelegate.

QDeclarativeVisualDataModel::setDelegate emits countChanged signal, but ListView is not listening to these signals at all (which seems a bit strange to me).

A simple test app attached.
