Uncaught TypeError: this.updater.enqueueCallback is not a function

When clicking on any timeslot, I get this error in my console:
Uncaught TypeError: this.updater.enqueueCallback is not a function
This is because the project is using React 15. Can you update the repo? Thanks for the wonderful project -- it's exactly what I needed!
