Colorbox sets up all its internal structures by looking at the DOM elements when you call it. This means that if you add the attributes after Colorbox's setup event, the plug-in won't see them.
Colorbox adds the next and previous buttons to groups created through a shared rel attribute. All you have to do is add rel="group1" where you have class="group1" in the first code sample and the buttons should appear.
