Android, unbind service and onServiceDisconnected problem

I'm not good in English, but I would try to explain my problem in good way.

So, the problem is:
1) I have a local service
2) I start it and then bound to it. 3) Problem appears when I am about to close that service. onServiceDisconnected method from my implementation of class ServiceConnection is never called. If I close it manually (from settings), or by unbindService, or by stopService, or by combination of unbindService and stopService - onServiceDisconnected still doesn't to be called. What am I doing wrong?

Short code is below:

protected ServiceConnection mServerConn = new ServiceConnection() {
    @Override
    public void onServiceConnected(ComponentName name, IBinder binder) {
        Log.d(LOG_TAG, "onServiceConnected");
    }

    @Override
    public void onServiceDisconnected(ComponentName name) {
        Log.d(LOG_TAG, "onServiceDisconnected");
    }
}

public void start() {
    // mContext is defined upper in code, I think it is not necessary to explain what is it 
    mContext.bindService(i, mServerConn, Context.BIND_AUTO_CREATE);
    mContext.startService(i);
}

public void stop() {
    mContext.stopService(new Intent(mContext, ServiceRemote.class));
    mContext.unbindService(mServerConn);
}

I'm testing this code under emulator of Android 2.2
