I am not sure if I understand the problem that you are describing, but if you encounter issues with scrolling back to top after focusing an input in the ListView that is further down the view, it is possible to be an issue with the emulated scrolling in mobile views. Try setting data-use-native-scrolling="true"
in the View, where your Mobile ListView is placed.
You can learn more about the specifics of native scrolling from this article:
