未执行nodejs socket.io发出

Question

I've got the problem that the second emit() in the following code (I have picked the important part if there is more needed just ask), which is sending a "stateChange"-Event, seems not to be executed. The "ID"-Event is received by the Server.

this.socket = io.connect('...');
this.socket.emit("ID", {canvasID: this.ID});

this.socket.on(PLACE_BUBBLE, function(data){
    var node = uCanvas.placeBubble(data.x1, data.y1);
    this.socket.emit("stateChange",
        {action : PLACE_BUBBLE, canvasID : this.ID, nodeID : node.nodeID, x : node.x, y : node.y});
});

The server is looking like this:

socketio.sockets.on("connection", function(socket){
    socket.on("ID", function(data){
       ...
    });
    socket.on("stateChange", function(data){
       ...
    });
});

placeBubble() is executed but there is simply no information send back to the server.

/solved: Problem was "this" in this.socket.emit which should be uCanvas.socket.emit(). This was the object holding the socket.
