Selection Handler of Google annotated timeline

In my Annotated timeline there is no annotation only data points. But I need to listen to the click events and need to know the date of the point where the user is clicking. How can I achieve this. In Google's JAVA API there is a select handler

addSelectHandler(new SelectHandler()
  {
   @Override
   public void onSelect(SelectEvent event) {
    // TODO Auto-generated method stub
    Window.alert("Date selected");
    searchCriteria.setDate(StaticUtil.setTimeZero(DataWareHouse.marketInfo.getValueDate(getSelections().get(0).getRow(), 0)));
    searchEvent.setSearchCriteria(searchCriteria);
    eventBus.fireEvent(searchEvent);

   }
  });

But its not working here. And from this JS API doc it seems that selectHandler only works on Annotations Markers. But I am not sure. Please share your experience on this regard.

There is no such event, see the complete list here: http://code.google.com/apis/chart/interactive/docs/gallery/annotatedtimeline.html#Events

The 'select' event is only for clicks on annotations but unfortunately not for points in the chart.

I assume Google is aware that many people look for this enhancement: http://groups.google.com/group/google-visualization-api/search?q=click+event+annotated

I would love to have this as well :)
