ListView detect itemsource changes

I've setup everything correctly using MVVM.
My ListView gets updated correctly when new Items are added to the List because my ViewModel implements INotifyPropertyChanged
Now I'd like to scroll to that item, which is the last in list when it is added.

I've thought about the propertychanged callback on the listview, but it is not called.
Is there a method to get a collectionchanged like behaviour?
