node.js eventEmitter + http.request

Hard one to spot ...

The problem is the this pointer from this.emit("tweets", tweets);. You are doing this call from within an anonymous callback passed to response.on, so this does not represent the Eventer object that you created. To solve it, you need to "save" the this pointer (a common practice).

var tweets = "";
var self = this;
....
self.emit("tweets", tweets);
