JSpinner Alternative ActionListener

In my program, I want to use JSpinner for a number. This number will later be used to calculate something. Each time the user presses one of the counter buttons (up or down), I want the result to be automatically updated. Since you cannot add an ActionListener to JSpinner (which, in my opinion, is very strange), I ask how to do something similar to this (I already have an ActionListener that can be changed in any other listener of course).

You can add ChangeListenerto the counter. This will work when the buttons are pressed (or direct editing of the field).

spinner.addChangeListener(new ChangeListener() {      
  @Override
  public void stateChanged(ChangeEvent e) {
    // handle click
  }
});

DocumentListener Document , .

Edit:

JSpinner.DefaultEditor editor = (JSpinner.DefaultEditor)number.getEditor();
JTextField textField = editor.getTextField();
textField.getDocument().addDocumentListener( new DocumentListener()
{
    public void insertUpdate(DocumentEvent e)
    {
        System.out.println("insert");
    }

    public void removeUpdate(DocumentEvent e)
    {
        System.out.println("remove");
    }

    public void changedUpdate(DocumentEvent e) {}
});
