title: Listen to scroll events of RadListView
body: <p>I need to bind some logic to RadListView's scrollOffset (change some opacity depending on how far user has scrolled), so I want to listen to scrolledEvent, as documentation says - <a href="https://docs.nativescript.org/angular/ui/professional-ui-components/ng-ListView/scrolling" rel="nofollow noreferrer">https://docs.nativescript.org/angular/ui/professional-ui-components/ng-ListView/scrolling</a></p>
  
  <p>I wanted to bind to it like to any other event in Angular, so by <code>(scrolledEvent)="onEvent($event)"</code>, but it doesn't work. Here's playground example, with working pullToRefresh event to compare to: <a href="https://play.nativescript.org/?template=play-ng&amp;id=HzbH8p" rel="nofollow noreferrer">https://play.nativescript.org/?template=play-ng&amp;id=HzbH8p</a></p>
  
  <p>It's possible that I'm missing something, e.g. pullToRefresh needs <code>pullToRefresh="true"</code>, but I don't see anything like that in documentation.</p>
