Current behavior:
ion-refresher is glitchy with OnPush change detection strategy. The arrow and the pulling text doesn't appear, and on the rare occasion it appears, the arrow doesn't change direction. The div with the class refresher-pulling stays display: none.

Edit: made a plunker that illustrates the bug. In my project I was marking the component for change detection manually at specific points, that's why my description differs slightly from the behavior of the plunker.

Expected behavior:
Same as with Default change detection strategy. Arrow and pulling text appear as I pull down, the arrow changes direction when I pulled far enough.

I'm having the same problem with the refresher using OnPush change detection strategy. Did you find any workarounds?

[horo42]

This solved the problem for me.

<ion-refresher (ionRefresh)="doRefresh($event)" (ionPull)="{}">

Thanks! This workaround made the pulling icon appear again, but after the refresh finishes the spinner keeps running in the background, just like on your plunker. Did you do something else to solve this too?

[horo42]

You should call the appropriate methods of ChangeDetectorRef if you use the OnPush strategy.

Thanks again! Now it's working perfectly!

Still an issue in 3.0.1. The (ionPull)="{}" hack works nicely.
