rear defrost plug question

The rear defrost plug terminal that goes glued to the glass came loose in one of the sides. I'm wondering how I should re-attach it to the glass.
If anyone knows what kind of compound or glue or whatever is needed please advise.

Goto the parts store and get some epoxy for glass, unless they sell something specific for your defrogger.
Not the wire or grid glue.
