I have it as a property, so I need to tell Qt the property has changed.
I could do connect(this, SIGNAL("rowsInserted(...), this,
SIGNAL(rowCountChanged());
I could do connect(this, SIGNAL("rowsRemoved(...), this,
SIGNAL(rowCountChanged());
+ rowsMoved + layoutChanged + modelReset..
so I deemed this easier.

beginInsertRows(QModelIndex(), 0, 1)
is saying you are inserting 2 rows, starting at 0 ending at 1. It's an annoying
QAbstractItemModel API.
