A problem with JScrollBar and the Jbutton

[cowboy]

In JscrollBar i can change the date value by the integrated buttons(1). This button increase or reduce the value of day of month by 1. I placed on my form another two buttons(2).this is a code described those behavior :

     
   SpinnerDateModel model = (SpinnerDateModel)jSpinner1.getModel();
        Calendar calendar = Calendar.getInstance();
        java.util.Date date=model.getDate();
        calendar.setTime(date);
        calendar.add(Calendar.HOUR, -1);
        

        java.util.Date initDate=calendar.getTime();
        java.util.Date earliestDate=calendar.getTime();
        java.util.Date latestDate=calendar.getTime();

        model = new SpinnerDateModel(initDate,earliestDate,latestDate, Calendar.YEAR);
  
        jSpinner1.setModel(model);

By this button i change a hour value by 1 up or down.But after i done it (change the hour value) i can not change the date value by the button 1 !!!.I press the upper-button on jscrollbar and it do nothing! Thats the problem?
