Checkbox menuItem Android and popup

I need to check the box when I click on the menu item, but for some reason it does not work for me. Can someone help with this?

            <group
                android:id="@+id/checkable_group"
                android:checkableBehavior="all">
                <item
                    android:id="@+id/silence_remove"
                    android:title="@string/silence_remove"
                    />
                <item
                    android:id="@+id/noise_suppression"
                    android:title="@string/noise_suppression"
                 />
            </group>

I open the menu with Popup

 private void showPopup(View v){

        popup = new PopupMenu(getActivity(), v);
        MenuInflater inflater = popup.getMenuInflater();
        inflater.inflate(R.menu.noise_suppression_menu, popup.getMenu());
        Log.v(LOG_TAG, ". showPopup");

        popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
            @Override
            public boolean onMenuItemClick(MenuItem item) {
                switch (item.getItemId()){
                    case R.id.silence_remove:
                        if(item.isChecked()){
                            item.setChecked(false);
                            Log.v(LOG_TAG, ". false");}
                        else{
                            item.setChecked(true);
                            popup.getMenu().getItem(0).setChecked(true);
                            Log.v(LOG_TAG, ". true");}
                        return true;
                    case R.id.noise_suppression:
                        if(item.isChecked())
                            item.setChecked(false);
                        else
                            item.setChecked(true);
                        popup.getMenu().getItem(1).setChecked(true);
                        return true;
                    default:
                        return false;
                }
            }
        });
        popup.show();
}

When I click on a menu item, it says "true", but does not note it in any way. And it is necessary that he remember what I have allocated.
