How would you assign a shortcut for this Enum list?

Hi guy’s,

Just trying to assign a single key shortcut for the Object/Display/ Maximum Draw Type/Wire and i know how to make the enum list to appear via a shortcut but i don’t want the list to show but only activate the Wire choice on selected object?

I tried to paste this command from the infoview but it doesn’t work ; object.draw_type = ‘WIRE’

Here my shortcut options box;
