Don't glue it - the winding stem may be broken..if you glue it, you won't be able to wind or adjust time.
I'm not really sure how to interpret your description of what is happening, but if something is really broken, glue will not work!
You'll need to find out what part broke and replace it. If the winding stem broke and a piece of the stem is stuck inside the crown and you can't get it out, then you'll need a new crown as well.
