got my Grant wheel,but.........

I received my Grant wheel from Jeg's.Fast delivery.When I was trying a few things out for fit the piece glued to the underside of the hornbutton came off.It was obviously glued there but I can't believe it came off so easily.Such a pain in the *** to send it back.Should I just try to glue it back on?Has anyone else run into this problem/has this type of wheel?What type of glue should I use.The button is plastic and the piece on the bottom is steel.Not too happy bout this.:angry7:
