using jquery bPopup plugin, cannot load content from button attribute data
<p>I really like demo of this plugin: <a href="http://dinbror.dk/bpopup/" rel="nofollow">http://dinbror.dk/bpopup/</a></p>

<p>I'd like to use it in my project, but I cannot seem to figure out how to make it run. Maybe pair of fresh eyes could help me :)</p>

<p>I would like to reproduce: <code>Example 4c, content: Simple jQuery popup that loads X content defined on the buttons data attribute (Content popup)</code></p>

<p><a href="http://jsfiddle.net/ubfQH/" rel="nofollow">http://jsfiddle.net/ubfQH/</a></p>

<p>Pop up never takes into consideration button attribute instead it always pops the div...</p>

<p>Can you help?</p>
