Can't get it to work with Zombie

[vlork]

Hi. I can't get this working. While in browser everything works, in Zombie it doesn't. I threw in a couple of console.log('connected') and console.log('click delay') in the server as well.

var browser = new (require('zombie'))()
browser.visit('http://localhost:8081')
browser.pressButton('#delay')

..shows that html works in Zombie, however no connection is made with socket.io?
