How to publish in the callback or it bug ?

[dogrocker]

I try to publish the data that received back to the broker but it seem like it loop multiple my publish data.

I test code like this.

void mqttData(void* response)
{
  RESPONSE res(response);
  debugPort.print("Received: topic=");
  String topic = res.popString();
  debugPort.println(topic);

  debugPort.print("data=");
  String data = res.popString();
  debugPort.println(data);

  mqtt.publish("test", "test");
  char buffTopic[64], buffPayload[64];
  topic.toCharArray(buffTopic, topic.length() + 1);
  data.toCharArray(buffPayload, data.length() + 1);
  mqtt.publish((const char*)buffTopic, (char*)buffPayload);
}

as expected it should send data to broker like.

olddata
test

but I got a lot of data like this.

olddata
test
olddata
test
olddata
test
olddata
test
olddata
test

What I'm wrong or this is a bug?
