How to use JP10 - I2C for Arduino

I need to make the WeatherPlus Board act as a I2C slave and arduino uno as master,

I try insert this code to WeatherPlus Board Using Arduino IDE

void setup() {

    ...
    Wire.begin(DEVICE_ADDRESS); //i tried to change many number as an address
    Wire.onRequest(requestEvent); 
    ...
}

void requestEvent() {
    ...........
    ...........
{

The problem is the master can't see the slave address But it can see all device on the WeatherPlus Board like this



I2C scanner. Scanning ...

Found address: 60 (0x3C)

Found address: 73 (0x49)

Found address: 87 (0x57)

Found address: 104 (0x68)

Found address: 119 (0x77)

Done.

Found 5 device(s).


Here this code is use i try to scan I2C address 

for (byte i = 8; i < 120; i++)

{

Wire.beginTransmission (i);

    if (Wire.endTransmission () == 0)

    {

        Serial.print ("Found address: ");

        Serial.print (i, DEC);

        Serial.print (" (0x");

        Serial.print (i, HEX);

        Serial.println (")");

        count++;

    } // end of good response

} // end of for loop

Serial.println ("Done.");


How should it do. I need suggestion.

Thanks for help.
