ReactJS and Django Problems

mery techsmas btw

So I was following this tutorial and was typing exactly what he types. When I load the page , and I click "Leave Room"; I get "this.props.leaveRoomCallback is not a function".

I even checked the code hosted on github and it looked the same as my code. I dont know what I am doing wrong.

Thank You.
