Usage instructions for JQFullCalendarPlugin

We're having a little trouble getting started with the JQFullCalendarPlugin. When we load the JQFullCalendarPlugin page in the System web, the following pops up:

readyState: 4
status: 200
but parsererror

When we click on "Close" in the popup, we get:

responseText: 
[
  {
    id: 1,
    title: 'Event1',
    start: 'May 27 2016',
    allDay: true
  },
  {
    id: 2,
    title: 'Workingday',
    start: 'May 27 2016 08:30:00',
    end: 'May 27 2016 15:00:00',
    allDay: false
  }
]

After closing the second popup, the calendar appears but doesn't show any events. We can navigate in the calendar and change between Day, Week, and Month, but can't enter new events.

Any help getting started would be greatly appreciated.
