Its not in the online documentation but have a look at the onMessageDelivered callback for the MQTTClient. In javascript at least it can be initialized like this...

myClient.onMessageDelivered = onMyMessageDelivered;

function onMyMessageDelivered()
{
    console.log("Your message was delivered");
}

If your send() is successful then the callback should be invoked.
