Android : Dialog sends data to the onActivityResult() for the activity

I have a problem here , I got a dialog with some options , one of them is to start an activity with the intent to get the contacts list:

Intent i = new Intent
                        (Intent.ACTION_PICK , ContactsContract.Contacts.CONTENT_URI);

                i.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_TYPE);

                getActivity().startActivityForResult(i, Request_contacts);

the above code doesn't call the onActivityResult on the dialog or in the fragment , it calls the onActivityResult in the activity , even if I removed getactivity() it still call the activity one!

I'm assuming I can't put a bundle and pass it the fragment at run time , then how can I pass the information that was in the onActivityResult to the fragment of that activity ?
