Add a playback capability to an IAd audio widget (for IBooks)

I have built a web page with an audio using html & JavaScript. I can playback and I can control the speed of the audio in the browser. When I add the same code in the iAd html widget, I loose the playback and speed control of the audio when I test on my IPAD. I need someone who can fix the playback capability as first step. I attached my html page and the same code in the widget. You can add your own audio file to test it.
