There may be more than just data-icon and data-iconpos attributes missing from the link tag - but those are immediately obvious.

example from my header section of my page

<a href="settings.html" id="link-1" data-icon="gear" data-transition="fade">Settings</a>
<h1>Page Title</h1>
<a href="about.html" data-rel="dialog" data-icon="info" data-iconpos="right" id="link-2">About</a>
