Pass Data to other Forms and update Form

In my App, I want users to be able to continuously add Songs to a List in FormA. FormB will then show the added Songs as Labels.

I know how to create the Label-List, but unfortunately, the added Songs won't show up in FormB. I need a way to update FormB every time a Song is added, so FormB is always up-to-date.

This is what I've tried:

public void createPlaylist() {
    for (int i = 0; i < songList.getSongList().size(); i++) {
        Button temp = new Button(songList.getSongList().get(i).toString());
        listCont.add(temp); //add Buttons to the List-Container for every Song in the List
    }
    centerCont.removeComponent(listCont); 
    centerCont.removeComponent(bottomCont); //remove Containers to add the updated ones (?)
    centerCont.add(listCont).add(bottomCont); //add updated Containers
}

This doesn't work, since the FormB which should show the new added Buttons isn't doing it.

How do I achieve this?

Thanks to Diamond Mubaarak, I managed to solve the problem. I just pass the Forms to each other, so I call FormA.revalidate(); in the FormB Method.
