Is it possible to use vanilla JavaScript scroll event with AngularJS framework?

I am attempting to track the window offset from the top of the document, but I am facing issues with jQuery scroll functionality. Can a vanilla JavaScript scroll event listener be used effectively within an Angular environment?

app.directive('owlCarouselItem', function($touch, $timeout, $rootScope, $window){
    return {
        restrict: 'C',
        transclude: false,
        link: function(scope, element) {
            // The scroll event in my directive is not triggering as expected
                $('html, body').on('scroll', function() {
                    if($(this).scrollTop() == 0){
                        console.log($(this).scrollTop());
                        canSwipeDown = true;
                    }else{
                        console.log($(this).scrollTop());
                        canSwipeDown = false;
                    }
                });

Give this code a try by utilizing angular.element($window):

.directive('scrollDir', function($window) {
    return {
        restrict: 'EAC',
        link: function(scope, attrs, element) {
            var canSwipeDown = false;
            // This section of my directive is where the scroll event does not trigger
            angular.element($window).on('scroll', function() {
                canSwipeDown = element.scrollTop() === 0;
                scope.$apply();
            });
        }
    };
});

You can attach the directive to the body tag like so: HTML:

<body scroll-dir>
