Carousel notifyOnSetChanged() not working

[sarahachem]

Hi I am using your library and it works very well until I try to update one of the carousel items programmatically.

I do the following when I create my Activity:

        listVideoLeft = (Carousel) findViewById(R.id.carousel1);
        photos = getPhotos(); //get all available photos
        updateList(index); // display only first 5 photos in the carousel (which are added to a tempPhotos list
        adapter = new MyAdapter(this, tempPhotos);
        listVideoLeft.setAdapter(adapter);
        adapter.notifyDataSetChanged();  

On click volume button down, I want to remove the first photo in tempPhotos and add a new one

@Override
 public boolean dispatchKeyEvent(KeyEvent event) {
        int action = event.getAction();
        int keyCode = event.getKeyCode();
        if (keyCode == KeyEvent.KEYCODE_VOLUME_DOWN)
                if (action == KeyEvent.ACTION_DOWN) {
                    if (photos.size() > 0) {
                        tempPhotos.remove(0);
                        tempPhotos.add(photos.get(newIndex)); 
                        adapter.notifyDataSetChanged(); 
                        listVideoLeft.invalidate();
                    }
         }
}

However, nothing changes in my carousel. Any ideas on the reason why it doesn't work in this case? as far as I know, in Adapter the notifyDataSetChanged in all you need to let the adapter know it's data has changed and it should update
