AngularJS window scroll event does not fire

I would just use

$(window).scroll(function () { alert('scrolled') })

OR you could use

angular.element($window).bind("scroll", function(e) {
    alert('scrolled')
})

there is no need for angular.element() inject $window to your controller, use the window.onscroll event

$window.onscroll = function (){ console.log('window was scrolled!'); };
