I am confused on how to refetch the resources by url (json feed).

This renders my calendar resources -

```
   $('#calendar').fullCalendar({
     ...
     resources: 'example.json?id=1',
     ...
   });

```

This documentation (<https://fullcalendar.io/docs/refetchResources>) says "If the resources option was specified as a JSON feed it will be requested again."

So I have a button that I want to click to change the resource url and reload the resource feed -

```
 $('.resource-button').on('click', function() {
    link = $(this).attr('href');
    $('#calendar').fullCalendar('refetchResources', {
      resources: link
    });
 });

```

Any idea why it doesn't reload the new resource link? The list of resources refreshes like it is doing something but the data stays the same.

Thanks
