I try to insert new element into RichTextArea but get an exception

public void onModuleLoad() {
final RichTextArea editor = new RichTextArea();
RootPanel.get("editor").add(editor);
Button button = new Button("Click Here");
button.addClickListener(new ClickListener() {
public void onClick(Widget sender) {
Document document =
IFrameElement.as(editor.getElement()).getContentDocument();
ButtonElement button = document.createButtonElement();
document.appendChild(button);
}
});
RootPanel.get("buttons").add(button);
}
