Not 100% sure about that method, but I believe the idea is that would
insert "empty" / "new" items (thus no data parameter).

In the past I've simply done:

model.beginInsertRows()
# code to modify underlying python list goes here, however you choose
# ....
model.endInsertRows()

Using these two methods causes the view(s) to requery the data
after endInsertRows() (given that you've implemented data() correctly)
