calendar: weekdays do not get translated when language is dynamically changed issue fix

Summary:
When calendar widget is already created and if we change language,
weekdays do not get translated because weekday string is statically
stored only during create.
Update the weekdays again when object is changed.

@fix

Test Plan:
1.Create and show calendar widget
2.Change the language
Weekdays do not get translated
