Using back button inside sub view

I have a specific page that I want full screen, so I hid the top bar and have a custom back button that calls ionicNavBarDelegate.back() and just like your example, it does nothing. I even tried to call the parent controllers ionicNavBarDelegate.back() with no success. I can make it go back using javascript but then the history gets all messed up. Any idea? Thanks

Does not anyone have a solution for this? It’s basically trying to have back button on pages with out a top menu.
