i don't know whether this is the best way but you can use broadcast to call parent component from child component.

 if (raw.scrollTop + raw.offsetHeight >= raw.scrollHeight) {
     $scope.$broadcast("call_func")
 }

component

.component('group', {
    templateUrl: '/djangotemplates/private/group/list.html',
    controller: function(
        $cookies,
        $http,
        $location,
        $scope,
        Flash,
        $animate,
        Group,
        $timeout,
        $rootScope
    ) {
        $rootScope.loadMoreGroups = function() {
            alert("loadmore");
        }
        $scope.$on("call_func", function(ev) {
            $rootScope.loadMoreGroups()
        })
    }
})
