title: Scroll event doesn't trigger
body: <p>I have a problem with <strong>scroll</strong> binding. I tried to use <a href="https://www.danyow.net/scroll-binding-with-aurelia/" rel="nofollow noreferrer">scroll binding</a> and <a href="http://ilikekillnerds.com/2016/02/using-event-listeners-in-aurelia/" rel="nofollow noreferrer">event listeners</a>  without luck. Using jquery doesn't work either. Any other event I tried works as expected, but with <strong>scroll</strong> it does literally nothing. No error, no message .. What am I missing?</p>
  
  <h3>Edit</h3>
  
  <p>Ok I made a mistake and didn't put it in the app.js and app.html as mentioned in examples but one layer under so there was no scroll event to catch on the element. If I put scroll.trigger there it works.</p>
  
  <p><strong>New question:</strong>
  Can scroll be triggered in children views? </p>
  
  <p>Eg.: lets say you have 2 view-models on 2 routes and you want one to trigger scroll event and the other not to. Can someone point me to right direction?</p>
