Adafruit RGB LCD Shield Kit & interrupt()

Good morning,

I am using the Adafruit RGB LCD Shield Kit and I would like to be able to use the buttons as an interrupt on a Arduino Uno. Int.0 refers to digital pin 2 and int.1 refers to digital pin 3. Is there a solution to attach I2C data wire (which are connected to the analog 4 pin) to an interrupt pin ? Any help out there will be appreciated. Camille.
