onRequestPermissionsResult not working in fragment

i'm trying to implement Marshmallow's permission support, but my code inside "onRequestPermissionsResult" is never called.

When working in an Activity its working but in fragment I am facing the problem i.e, the control is not coming in onRequestPermissionsResult()

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                            mCheckPermission();
                        }

In the mCheckPermission():-

public void mCheckPermission() {
        if (ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_FINE_LOCATION)
                != PackageManager.PERMISSION_GRANTED || ContextCompat.checkSelfPermission(getActivity(),
                Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            requestPermissions(new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION},
                    PERMISSION_REQUEST_COARSE_LOCATION );

        }
    }

The dialog pops up with 2 buttons. DENY and ALLOW. When clicking on the button the controls is not coming inside the onRequestPermissionCheck();

@Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);

        switch (requestCode){
            case PERMISSION_REQUEST_COARSE_LOCATION: {
                if (grantResults.length > 0
                        && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                    Toast.makeText(getActivity(), "permission granted", Toast.LENGTH_LONG).show();
                    //call your action

                } else {
                    Toast.makeText(getActivity(), "permission denied", Toast.LENGTH_LONG).show();
                }
                break;
            }
        }
    }
