in Q2, the endless scrolling was re-implemented in order to support virtualization mode. This lead to some breaking changes in the way the datasource is configured - I would like to suggest that you look through our updated documentation and demos in case something does not work as expected after the upgrade.
As far as I can see, the new implementation eliminates the need for this workaround. Re-populating the datasource with new data should cause the listview to refresh and scroll to the top automatically.
