[GoogleCodeExporter]

What steps will reproduce the problem?

1. Go to sender web page - see attached simple_sender.html, launch debug console
2. Connect to Chromecast, load media file
3. Perform commands on media: pause, play, seek, set volume, observe on debug 
console media status updates

What is the expected output? What do you see instead?

media object has update listener callback, this callback is never called

Please provide any additional information below.

We want to obtain MediaStatus object from receiver to sender.  I provided basic 
sender page which talks to basic receiver that is quoted in "CastVideos-chrome" 
code sample.  Is this a bug or something is missing in our sender / receiver 
code?
