@TheBlasfem you beat me to it haha! I noticed though that your fix doesn't address the fact that no event listener was added for the 'hidden' event to begin with. Also, the event name is actually hidden.bs.modal. I've made those changes in mine in addition to responding to the same onHidden prop you also implemented.

nice catch @MarkMurphy, thanks for notice me, we can continue with your solution
