Its always provided via onDtaChanged, but you can invoke that manually from
the ListModel. AbstractListModel will provide a setData() method to push
data to the views.
The ability to push data was one of the reasons we decided to have
ListHandlers (views) subscribe to the ListModel instead of just sending a
simple request, like they do with the PagingScrollTable.
