Can someone explain me how to create a jquery UI datepicker with both properties `changeMonth` **and** localization?

I have these two lines of code:

```
$('.datePicker').datepicker($.datepicker.regional['en']);
$('.datePicker').datepicker({ changeMonth: true });

```

I'd like to merge them into a single line, since the second one seems to fail if not called when and only when constructing the datepicker for the first time. Unfortunately, I can't do this since I don't know to which property assign the `$.datepicker.regional['en']`.

Thanks.

I've already tried this, with no success: [jQueryUI datepicker: Month/Year Menus with Localization](https://stackoverflow.com/questions/14000128/jqueryui-datepicker-month-year-menus-with-localization?rq=1)
