title: Audio event not firing when bind dynamically
body: <p>I have an audio element <code>&lt;audio&gt;</code> (I am appending it to body via js) which is playing audio. If I bind event <code>onplay</code> in the html then it works.</p>
  <pre><code>&lt;audio onplay=&quot;alert('t')&quot; .... its working...
  </code></pre>
  <p>but if I am binding it via js then its not working.</p>
  <pre><code>document.getElementById('audio1').onplay = function() { alert('t'); }; //..... not working
  </code></pre>
  <p>Any solution?</p>
