Tvheadend

Tried to convert the htsp hello method from johns android project to javascript. Did not go to well, anyone see what went wrong?
Goal is to get a "Welcomed client software: org.me.tvhguide" on the tvheadend server..

I get;
[INFO]:htsp: Got connection from 192.168.1.101
[INFO]:htsp: 192.168.1.101: Disconnected

I want;
[INFO]:htsp: 192.168.1.101: Welcomed client software: org.me.tvhguide

(Can i enable more logs?)

code;
