I'm not sure about why you need this mark-up for action(showsmartInfo on hover). But following below steps can get you the code/markup you're looking for.
Include this custom non-auto control in a section and add the actions in the action tab of the control properties panel.
During run-time you should see the markup generated if you inspect using developer tools. If the mark-up is not generated, try by chnaging the 'Applicability' field on actions tab of properties panel to 'both' and reload the screen in run-time.
