inside the event listener (which is not an MVVM command handler) method you have to trigger the notify change programmatically.

if (Messagebox.Button.OK.equals(event.getButton())) {
    //do something here, if success:
    setWinvisible(false); 
    BindUtils.postNotifyChange(null, null, YourViewModelClass.this, "winvisible");
} else {
    //do something
}
