glue question

[doogloose.livejournal.com]

hey - a little while ago i posted a pic of some hair clippies i made (pic). they were made from bead halves (glass beads) glued onto those cheap metal clips you can buy at dollar stores. don't know what kind of metal it is. i used super glue - the gel kind that is supposed to bond really good even when you have a slightly uneven surface (it fills in the gaps or something?) - well, the beads didn't stay on. some of them fell off as soon as i tried to open the clips; the rest were *very* easily pulled off.

what's the right glue to use to bond glass to metal?
