Android - doesn't come into success callback

I am putting a twitter login button inside a fragment of navigation drawer. I can see the login button, click ‘Allow’ on the registered twitter account. But, I am unable to see that it comes into success callBack. It happens only when I use the button inside fragment. It works fine when used in Activity.

Fragment:

public class HomeFragment extends Fragment {
    // TODO: Rename parameter arguments, choose names that match
    // the fragment initialization parameters, e.g. ARG_ITEM_NUMBER
    private static final String ARG_PARAM1 = "param1";
    private static final String ARG_PARAM2 = "param2";

// TODO: Rename and change types of parameters
private String mParam1;
private String mParam2;

private OnFragmentInteractionListener mListener;
private static final String TWITTER_KEY = "zzz";
private static final String TWITTER_SECRET = "zzzz";
final static String TAG = "TwitterFabric";
private TwitterLoginButton loginButton;

/**
 * Use this factory method to create a new instance of
 * this fragment using the provided parameters.
 *
 * @param param1 Parameter 1.
 * @param param2 Parameter 2.
 * @return A new instance of fragment HomeFragment.
 */
// TODO: Rename and change types and number of parameters
public static HomeFragment newInstance(String param1, String param2) {
    HomeFragment fragment = new HomeFragment();
    Bundle args = new Bundle();
    args.putString(ARG_PARAM1, param1);
    args.putString(ARG_PARAM2, param2);
    fragment.setArguments(args);

    return fragment;
}

public HomeFragment() {
    // Required empty public constructor
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if (getArguments() != null) {
        mParam1 = getArguments().getString(ARG_PARAM1);
        mParam2 = getArguments().getString(ARG_PARAM2);
    }

}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    View rootView = (View) inflater.inflate(R.layout.fragment_home, container, false);


    // Inflate the layout for this fragment
    TwitterAuthConfig authConfig = new TwitterAuthConfig(TWITTER_KEY, TWITTER_SECRET);
    Fabric.with(getActivity().getApplicationContext(), new Twitter(authConfig));


    loginButton = (TwitterLoginButton) rootView.findViewById(R.id.login_button);
    loginButton.setEnabled(true);
    loginButton.setCallback(new Callback<TwitterSession>() {

        @Override
        public void success(Result<TwitterSession> twitterSessionResult) {
            Log.d(TAG, "callback success");
            Log.d(TAG, twitterSessionResult.toString());
             TwitterSession session =
                    Twitter.getSessionManager().getActiveSession();
            TwitterAuthToken authToken = session.getAuthToken();
            String token = authToken.token;
            String secret = authToken.secret;
            Log.d(TAG, "token: "+token);
        }

        @Override
        public void failure(TwitterException e) {
            Log.d(TAG, "callback failure");
        }
    });

    return rootView;
}

// TODO: Rename method, update argument and hook method into UI event
public void onButtonPressed(Uri uri) {
    if (mListener != null) {
