Dear @aarontam ,

Yes we can do that but it will not work if the application developer creates a DatePicker component and sets the locale to 'th-TH'. localeChanged function gets called only when locale is changed. It doesn't get called at the time of DatePicker component creation.
That's why i have added this setLocale function in L116 and L190.
