onactivityresult не вызывается в DialogFragment

Question

Я показываю DialogFragment из действия и хочу выполнить какое-то действие по нажатию кнопки, но мой метод onActivityResult никогда не вызывался во фрагменте.

mHelper.launchPurchaseFlow(activity, itemForPurchase, 10001,mPurchaseFinishedListener, payload);

вышеуказанная функция работает нормально, и мой платеж также успешен, нопри повторном открытии приложения оно будет потреблять сумму.

public class InstantDealPopup extends DialogFragment implements OnClickListener {
    private static IabHelper mHelper;
    private static final int ID_IV_CLOSE = 1;
    private static final int ID_IV_ACCEPT_BUY = 2;
    private static final int ID_IV_REJECT_BUY = 3;
    private static Activity activity;
    private static SharedPreferences prefs;
    private static SharedPreferences.Editor prefEditor;
    private static String itemForPurchase;
    private static int item;
    private static int credit_amount = 1;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setStyle(STYLE_NO_FRAME, R.style.FragmentTheme);
        initInApp();
        setCancelable(false);
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        System.out.println("onActivityResult(" + requestCode + "," + resultCode
                + "," + data);
        // Pass on the activity result to the helper for handling
        if (!mHelper.handleActivityResult(requestCode, resultCode, data)) {
            // not handled, so handle it ourselves (here's where you'd
            // perform any handling of activity results not related to in-app
            // billing...
            super.onActivityResult(requestCode, resultCode, data);
                  } else {
            System.out.println("onActivityResult handled by IABUtil.");
        }
    }
