Event Handler not working on second time

Simple code snippet:

@Component(immediate = true)

@Service

@Property(name = EventConstants.EVENT_TOPIC, value = "com/day/cq/wcm/core/page")

public class SimpleResourceListener implements EventHandler{

  public SimpleResourceListener(){

  System.out.println("inside construc");

  }

  private Logger log =LoggerFactory.getLogger(this.getClass());

  public void handleEvent(Event event) {

  // TODO Auto-generated method stub

  System.out.println("inside hanlder");

  }

Now when I create a page, this handler reacts and logs the string "inside handler". Now when I activate the page second or third time, the Event handler does not react
