The channel object is returned when you subscribe to a channel.
For instance:
var dispatcher = new WebSocketRails('localhost:3000/websocket');
var awesome_channel = dispatcher.subscribe('awesome_channel');
awesome_channel.bind('event', function(data) { console.log('channel event!'); });
awesome_channel.trigger('awesome_event', awesome_object);
