List rebuild fails if resulting list is empty

Problem/Motivation

Whenever I delete the last item from my Favorites' list, I have to reload the page for the changes to be visible. It is prevented by an if statement in the rebuild function.

    rebuild: function(data) {
      if (data.list) {
        Drupal.detachBehaviors($('div#favorites-list'));
        $('div#favorites-list').html(data.list);
        Drupal.attachBehaviors($('div#favorites-list'));
      }
    },

Proposed resolution

Remove the if (data.list) statement. If the list is empty, it has to be rebuilt.
