On-scroll-complete doesn't appear to work on ion-content

I’m attempting to have a function run after the user has scrolled down or up a page. The current hierarchy of my app is:

ion-side-menus > ion-side-menu-content > ion-content > [actual content]

with the ion-content having the following attribute:

on-scroll-complete="onComplete"

in my app.js, I have the following:

.controller('HomeCtrl', function($scope, $ionicScrollDelegate) {
	$scope.data = {
		title : 'Top: ?'
	};
	$scope.onComplete = function() {
		$scope.data.title = "Top : " + $ionicScrollDelegate.getScrollPosition().top;
	};
});

However, this function doesn’t run at all. Is this the correct way to be going about it or is there something I’m missing? I’m very new to Ionic, so perhaps I’m placing the function in the wrong scope?

Any help or guidance is appreciated!

Sorry, I should have created a Codepen to illustrate my issue.

Here we go.

Hmm, seems that it does work, but there’s an issue with binding to it I guess.

Can you open an issue for this? I’m a bit confused as well.
