Browser scroll event doesn't fire often enough on iOS and Android devices

I'm developing a one-page site using jQuery, greensock and scollorama.

It doesn't exactly need to support mobile browsers but it would be nice if it would work on the iPad - so with that in mind I started testing on various mobiles and tablets.

The problem I ran into is that scrollorama relies on the scroll event being fired fairly often as this is what the animations are hooked into - however, when using a touch screen, the browsers only seem to fire the scroll event when you start the drag and when you stop - this is consistent across Opera Mini, Chrome, Safari, FF Mobile.

To get my page to atleast partially work, I need to come up with something that will let me fire the scroll event more often - does anyone know how?

P.S I've tried using iScroll as the scrollorama docs suggest, however that didn't work and instead broke the animations and made scrolling impossible - I'm sure the plugin itself works but it doesn't seem to work well with what I've already got. I'm looking for something less involved than a plugin, just a snippet to trigger the scroll event ideally.

TL;DR

Devices with touch screens seem to only fire the javascript scroll event once or twice during a drag. Is there a simple patch I can do in JS or jQuery which will fire the scroll event more often?

Update: I've tried hooking into the touch events and triggering browser scroll with them like so:

    $(document).on('touchstart touchend touchmove', function(){
        $(window).trigger('scroll');
    });

This seemed to give me better results on Android using Firefox, although I don't think it's firing as often as I'd like it's better than nothing.

I'll test in other browsers and see if this helps.

Update 2:

The above code helped alot on FF on Android, but not on iPhone. I tried adding handlers for gesture events that iPhone fires, but no change.

$(window).on('touchstart touchend touchmove mousewheel touchcancel gesturestart gestureend gesturechange orientationchange', function(){
        //alert($(window).scrollTop());
        $(window).trigger('scroll');
    });
