Title: Fix for U4-3831.  

It appears the add button (``) is submitting the entire page, rather than just calling `add()` on the containing form. This makes it impossible to add items in some browsers. This commit removes the containing form, changes the submit button to just a `` and adds `ng-click` with `$event.preventDefault()` to prevent submitting the entire page.
