Inserting a custom component in cells of JTable ?

I've already seen some examples with inserting of JComboBox and JCheckBox, but when I insert my own component there is a problem: I can click on the checkbox and button on my component but the component has the same hash-code for all cells of the table. In this case the state of every JCheckBox (selected property) is not saved because all links point to the same object (the same component). How to solve this problem ?

Here how I add a renderer and editor:

table.getColumn(0).setCellRenderer(new MyCellComponentRenderer());

table.getColumn(0).setCellEditor(new MyCellComponentEditor(new JCheckBox()));

Here is my renderer class:

public class MyCellComponentRenderer extends MyComponent implements TableCellRenderer {

      public MyCellComponentRenderer() {
       // setOpaque(true);
      }

      public Component getTableCellRendererComponent(JTable table, Object value,
                       boolean isSelected, boolean hasFocus, int row, int column) {
        if (isSelected) {
          this.setForeground(table.getSelectionForeground());
          setBackground(table.getSelectionBackground());
        } else{
          setForeground(table.getForeground());
          setBackground(Color.white);
        }


        return this;
      }
    }

Editor:

public class MyCellComponentEditor extends DefaultCellEditor {

    private MyComponent myComponent;

    private boolean isChecked;
    private boolean isPushed;

    public MyCellComponentEditor(JCheckBox checkBox) {
        super(checkBox);

        myComponent = new MyComponent();
        myComponent.getCheckBox().setOpaque(true);
    }

    @Override
    public Component getTableCellEditorComponent(JTable table, Object value,
            boolean isSelected, int row, int column)
    {
        if (isSelected) {
            myComponent.setForeground(table.getSelectionForeground());
            myComponent.setBackground(table.getSelectionBackground());
        } else {
            myComponent.setForeground(table.getForeground());
            myComponent.setBackground(Color.orange);
        }

        return myComponent;
    }

    @Override
    public Object getCellEditorValue() {
        if (isPushed) {
        }
        isPushed = false;
        return new String("");
    }
    @Override
    public boolean stopCellEditing() {
        isPushed = false;
        return super.stopCellEditing();
    }
    @Override
    protected void fireEditingStopped() {
        super.fireEditingStopped();
    }
}

Component:

public class MyComponent extends JPanel
{
    private JButton button;
    private JCheckBox checkBox;
    private JLabel label1;
    private JLabel label2;

    private boolean state;

    public MyComponent() {

        button = new JButton("A");
        checkBox = new JCheckBox("B");
        label1 = new JLabel("1");
        label2 = new JLabel("2");

        this.add(button);
        this.add(checkBox);
        this.add(label1);
        this.add(label2);

        button.setOpaque(true);
        button.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e)
            {
                JOptionPane.showMessageDialog(button,button.hashCode());
            }
        });
    }

    public JCheckBox getCheckBox()
    {
        return checkBox;
    }

    public void setCheckBox(JCheckBox checkBox)
    {
        this.checkBox = checkBox;
    }

    public void setState(boolean state)
    {
        this.state = state;
        checkBox.setSelected(state);
    }

}
