Scrolling effect on ionic? no luck with angular-scroll-animate


I’m trying to add some effects on scrolling, my page is made of pictures and text, and i’d like to have some kind of parralax/fade/whatever cool effect on images when scrolling down.
So i found this :
which seems nice so i gave it a try.
It doesn’t seems to work in ionic, “when-visible” listeners for all elements are called as soon as the page is loaded, and not when divs are individually displayed.

Am i missing something?
