title: accessoryButtonTappedForRowWithIndexPath is not being called
body: <p>I have my app perfectly working on the simulator and on the iPhone OS 2.2.1 device.
  But I as well have a device with iPhone OS 3.0 installed. And when I tap on a disclosure button, the accessoryButtonTappedForRowWithIndexPath method is not being called, however color of a disclosure button becomes darker.</p>
  
  <p>Has anyone faced such an issue?</p>
  
  <p>How can I solve this problem?</p>
