Events+ registration form modification

Hello guys!

I need to collect some data from people who are enrolling in the event (class at my situation), it is crucial to have billing address as well as phone number just in case. I have completed setting up simplr plugin, but when I click on 'I'm attending" and choose to register with blog, it still have pop up with email and password instead of redirecting to page with registration form. My question would be how should I setup events+ and simplr to work together.

Thank you!
Cheers Alexey
