Subscribe to a Webhook response triggered by a specific device

So I have been thinking and messing around and read this from @ScruffR

made me think... "what about using Particle.subscribe() and using the device's own ID" like this:

void setup()
{
  myDeviceID = System.deviceID();
  Particle.variable("deviceID", myDeviceID, STRING);
  Particle.variable("SunriseTime", &message, STRING);
  Particle.subscribe("hook-response/sun_time", sunTimeHandler, myDeviceID);
}

but, it doesn't seem to respond...

entire test code:

struct deviceTime{
  int Hour;
  int Minute;
};

deviceTime sunrise = {6,0};
deviceTime sunset = {18,30};

String myDeviceID;

char message[40] = "No Time Values Recieved";

void setup()
{
  myDeviceID = System.deviceID();
  Particle.variable("deviceID", myDeviceID, STRING);
  Particle.variable("SunriseTime", &message, STRING);
  Particle.subscribe("hook-response/sun_time", sunTimeHandler, myDeviceID);
}

void loop()
{
  static unsigned long myTimer = 0;
  if(millis() - myTimer > 60000UL)
  {
    Spark.publish("sun_time", "{ \"myCity\": \"Weston\", \"myState\": \"FL\" }");
    myTimer = millis();
  }
}

void sunTimeHandler(const char * event, const char * data)
{
  String sunriseReturn = String(data);
  char sunriseBuffer[40] = "";
  sunriseReturn.toCharArray(sunriseBuffer, 40);
  sunrise.Hour = atoi(strtok(sunriseBuffer, "\"~"));
  sunrise.Minute = atoi(strtok(NULL, "~"));
  sunset.Hour = atoi(strtok(NULL, "~"));
  sunset.Minute = atoi(strtok(NULL, "~"));
  char buffer[60] = "";
  sprintf(buffer, "Sunrise: %02d:%02d, Sunset: %02d:%02d", sunrise.Hour, sunrise.Minute, sunset.Hour, sunset.Minute);
  Particle.publish("pushover", String(buffer), 60, PRIVATE);
  strcpy (message, buffer);
}

though the hook does fire and of course the myDeviceID is correct in the response (redacted):

{"name":"sun_time","data":"{ "myCity": "Weston", "myState": "FL" }","ttl":"60","published_at":"2015-08-29T13:21:21.314Z","coreid":"myCoreID"}
{"name":"hook-response/sun_time/0","data":""7~00~19~44~"","ttl":"60","published_at":"2015-08-29T13:21:24.500Z","coreid":"undefined"}

but you can see that I get a:"coreid":"undefined" argument returned in the response...

Am I missing something here?

webhook:
