Title: [FIX] incorect aria-label on DropDownButton's popup.

Sample representing problem is here:
http://jsfiddle.net/7FVV6/3/

aria-label attribute was incorrectly set as id attribute because of missing label or name
which is not beign provided when using it in scenario such as:

Register

Tooltip text

Fixed by adding fallback value representing parents's label.
