Putting a FAB on top of ionic slide on fixed place


I have a simple ionic-slides implementation in Ionic2. I want to put a Floating Action Button (FAB) in the right upper corner which stays there for all the slides (and doesnt slide away and returns). I managed to get it on top of all slides by giving it a high z-index. Nevertheless, the button remains unresponsive to clicks. Likely becuase the ionic-slide catches all mouse events and doesnt bubble it.

Anyone having a suggestion on how to achieve a FAB on a slide which stays on top and doesnt slide away.

Alternative route would be to place it outside the slidebox, but I rather put it on top.
