Fix the logic bug

Was working because probably that branch of 'if-logic' is never executed before. 

So a minor expirity changes trigger that if-logic and cause all of the error. 

`self.render` <-- will call express's request method, so basically dump output and exit (that's why it only display one theater and exit)

`render` <-- will call object's method that actually call a proper callback 

Weird bug indeed :+1:
