Facebook request data field

Question

I would like to include some custom data that I want to pass to the invitee along with the invite/request. Such that whenever the invitee accepts the invite he can use that custom attribute. I have tried placing this information in the 'data' field but am unable to access it when the invitee clicks on the request notification.

FB.ui(                  
{
    method: 'apprequests', 
    message: 'You should learn more about this awesome game.',
    data: myCustomInformation
});

So how can I access this 'data' when the invitee accepts the invite request.?
