"open dialog" button displaying as url instead of button

"open dialog" button displaying as url instead of button

Hello - I'm using the following anchor per the jQuery Mobile website to implement a basic modal dialog:

<a href="http://www.google.com" data-rel="dialog">Open Dialog</a>

Unfortunately, this is only displaying an anchor, not the Open dialog button.  Also, when I click on the url, the page redirects to the url in full page mode instead of displaying the redirect url in a dialog.  What am I missing?  I have attached a text file of my webpage....
