The view usually only does that if its notified that the layout of the
expanded index changed, in particular rows/columns have been added/removed
to it or if your model emits the layoutChanged signal for it. So check
that, if you can't spot any error provide a simple self-contained example
which simply does the changes your real model does triggered by a timer or
so.
