HomePage pushed multiple times

[surr34]

When I press "Sign In" I am redirected to the Homepage as expected.
After I hit the back button and "Sign In" again the Homepage is pushed multiple times and I need to hit "back" quite often to get back to the Login Screen.

I think this is due to reusing the buttonController over and over again without resetting it.
Adding buttonController.reset() here fixes the error at least for me.
