Roller in upper rack cracked where screw entered

Removed endcap on rack, took out old part, had to glue together the support in the middle of the roller because the part that came was different than what was original.
I did not order the proper screw or something, because there was nothing online showing exact roller with the correct female screw receptacle. Also, screw ordered was like old one, but did not work in roller assembly that came.
Not sure if glue will hold up long under heat of dishwasher.
