title: How to add controls to ItemTemplate (Repeater) at run time?
body: <p>I'm desinging a rich repeater control which needs some controls (specifically just an unordered list) added to it at runtime.<br/><br/>
  The solution I've opted for is to inject the nesseccary markup, onInit, into the header, item and footer templates respectively.<br/>
  I can get the templates out (using InstantiateIn) and then add the markup as needed, but I don't know a way to add the template back in to the repeater?</p>
