Angular helps you organize and test your code. How did you test your 50+ onclick functions? Did someone come after you to do maintenance and agree the jQuery was the way to go?
I wouldn't test 50+ onclick functions. I'd used event delegation to assign the click handler to the appropriate parent element. I'm not experienced with Angular, but the last time I checked it didn't support event delegation :(
Are you saying you are writing tests for all of your 50+ ng-click functions then? What's the difference?
