During a game, the DM is always right. Even if they're wrong. Hopefully they will listen to other people's opinion, but sometimes there is just no "right" answer.
I don't have a problem with you're DM's ruling and how he envisions the spell working is completely legitimate. I may have ruled differently, that the magic was on the demon and someone on his plane would have had to cast the dispel. But I'm not the DM so my opinion doesn't really matter.
