Hi. Can I disable server feature on figwheel (leave only websocket one)?

Hi, I'm really sorry for asking such a basic question, but I cannot get :on-jsload to call my mount function. (https://github.com/hoopes/povon-cljs to see the very simple example of my ineptitude). Should :on-jsload have a string, or a reference to the actual function as the value? I've read the README, and I just can't see what I'm screwing up. I've been staring at this problem quite a while, and posted here as a last resort Thanks in advance for any answers.
