Creation and Event linkage (JavaME CLDC 1.1 MIDP 2.0)

Hi people!
Lets me try to explain whats my problem:
Ive make this interface below:

In a Form I implements this interface because I need a CustomButtom class called CommandButtom Ive created call this methods when that methods occurs on the buttom.
See bellow:

public class CommandButtom extends CustomItem 
{
	public int tag;
	private int w, h;
	private Displayable listener;
	
    public CommandButtom(String label)
	{
		this(label, null, 40, 20);
	}
    public CommandButtom(String label, Displayable listener)
	{
		this(label, listener, 40, 20);
		tag = 0;
    }
    public CommandButtom(String label, Displayable listener, int w, int h)
	{
		super(label);
		this.listener = listener;
		this.w = w;
		this.h = h;
		setItemCommandListener((ItemCommandListener) listener);
		tag = 0;
    }
	
    protected int getMinContentHeight()
	{
		return 20;
    }

protected int getMinContentWidth()
	{
		return 40;
    }

protected int getPrefContentHeight( int width )
	{
        return getMinContentHeight();
    }

protected int getPrefContentWidth( int height )
	{
        return getMinContentWidth();
    }

protected void paint( Graphics g, int width, int height )
	{
        g.setColor(127, 127, 127);
        g.fillRect(0, 0, width, height);
        g.setColor(255, 255, 255);
        g.drawRect(0, 0, width, height);
    }

protected void pointerPressed(int x, int y)
	{
		//Here I need to call the event
	}

protected void pointerReleased(int x, int y)
	{
               //And here too
	}
	
	
}

You see? I need to call this events so my form will do some action. Ive a private variable called "listener" thats a reference to the Form. Do you undestand ? Its so difficult explain a thing like tha when your first language is not english hehheeh. Thanks in advance!

Do you use this method?

javax.microedition.lcdui.Item.notifyStateChanged()

javax.microedition.lcdui.CustomItem:

Finally, subclasses are responsible for calling Item.notifyStateChanged() to trigger notification of listeners that the CustomItem's value has changed.

Thanks for helping! My solution for this problema was:
An interface:

And a method call to the Form who implemented the interface:

That's it!
Thanks!
