MessageAPI android Wear, can send message to wearable, but wearable cannot send message back

So I have an application that can communicate just fine from phone to my LG G Watch. The issue is that I cannot send a message back. Here is my code for sending from the wearable, which always indicates that the message has been sent:

public void oops(View view){
    Thread thread = new Thread(new Runnable() {
        @Override
        public void run() {

            NodeApi.GetConnectedNodesResult nodes = Wearable.NodeApi.getConnectedNodes(googleApiClient).await();
            for (Node node : nodes.getNodes()) {
                MessageApi.SendMessageResult result = Wearable.MessageApi.sendMessage(googleApiClient, node.getId(), "/start/MainActivity", "Hello".getBytes()).await();
                if (!result.getStatus().isSuccess()) {
                    Log.e("INFO", "ERROR");
                } else {
                    Log.i("INFO", "Success sent to: " + node.getDisplayName());
                }

            }
        }
    });
    thread.start();
}

I always get the success message after sending. Here is the receiver service at the other end:

    public class Reciever extends Service implements MessageApi.MessageListener {
    public Reciever() {
    }

    @Override
    public IBinder onBind(Intent intent) {
        // TODO: Return the communication channel to the service.
        throw new UnsupportedOperationException("Not yet implemented");
    }

    @Override
    public void onMessageReceived(MessageEvent messageEvent) {
        Log.i("INFO", "We got it!");
    }
}

This is the exact same code that I use in my watch application, which receives messages just fine. I'm sure that the service is properly started and declared, and that both applications have the same ID. Any suggestions?

I figured out that you have to have register the listener in onBind or OnCreate:

Wearable.MessageApi.addListener(googleApiClient, this);
