Current behavior
Switching the locale (e.g. with a button) does not change the translation (Month, Days) in the calendar popup.
After directing into the next month, the translation will change into the correct language.
Day names stay in the wrong language.

Expected behavior
The calendar popup should update when switching the locale.

Please tell us about your environment:

• **React version:**16.4.1

• **PrimeReact version:**1.6.0

• Browser: [all]

• Language: [all | TypeScript X.X | ES6/7 | ES5]

Calendar is reimplemented in 2.0.0-beta.1 which also fixes this.
