Your code looks fine, though I'd suggest taking out the moduleName property as that's really only for backwards compatibility with PocketBrowser.
You might want to consider turning on logging (INFO level) and observing what issues come out there.
I'm attaching my test page if it helps also
NB: You'll need to be using a DCR7000-100 or DCR7000-200 attachment.
