title: implement infinite scroller in angular2
body: <p>I would like to implement infinite scrolling for an *ng-for of DIVs in angular2 component. For this I need to somehow hook to the window onScroll event via angular method. Then in angular I will be able to load more items into the data items array when user has scrolled pass some point of the page.</p>
  
  <p>Anyone has ideas how to hook to the window.scroll event from angular (inside ng2 component)?</p>
