Jquery datepicker beforeShowDay after initializing

Question

When I am setting beforeShowDay after initializing it doesn't work ``` $("#dater").datepicker(); $("#dater").datepicker({ beforeShowDay: renderCalendarCallback }); ``` It will work when I will change and call beforeShowDay for first time ``` $("#dater").datepicker({ beforeShowDay: renderCalendarCallback }); $("#dater").datepicker(); ``` How can I fix this to call beforeShowDay in first scenario too? Note that I can't remove first initialization, because it is unreachable for me. You can test this scenarios in this jsfiddle http://jsfiddle.net/b6V3W/352/

Accepted Answer

For setting options after initialization, you need to use the `option()` method.

```
$('#dater').datepicker( "option", "beforeShowDay", renderCalendarCallback );
```
