What glue did you use?
I made a similar repair but with a smaller break using superglue (cyanoacrylate), held perfectly. However, I reinforced the broken part with a piece of a plastic card glued to the side. Consider doing that if this doesn't hold.
I'd be concerned that the rough surface you seem to have now will be hard to clean and may get very nasty. Other than that, if it works it works.
