title: Tell screen reader that page has changed in Backbone/Angular single-page app
body: <p>Imagine you have a simple, single-page application - regardless of whether it was written using Backbone, Angular, Ember or anything else.</p>
  
  <p>How can you tell a screen reader that we've changed 'page' when a route is followed?</p>
  
  <p>In a classic application, when I navigate from <code>/index.html</code> to <code>/about.html</code> the screen reader obviously detects the page change, and re-reads as you'd expect.</p>
  
  <p>In my Backbone application though, when I follow a route I cannot work out how to trigger a 're-read'. I've tried triggering a <code>focus</code> event which I'd seen somewhere, but that doesn't seem to work.</p>
  
  <p>Note: I'm currently testing with NVDA/Chrome.</p>
