There is an appendChild method though:

roles.get(1).appendChild(new Element("user").appendChild("myself"))

or some such (not sure exactly what you want but should be something like

Only because you haven't added anything yet. You can append a child to
an empty element, just as you might add an item to an empty list, and
then it won;t be empty any more. :-)
