Uncaught TypeError: $ (...) .fullcallendar is not a function

I've tried everything to make fullcalendar work, my code looks like this:

@{
    ViewBag.Title = "Calendario";
    //Layout = "~/Views/Shared/_Layout.cshtml";
}

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">
<link href="http://cdnjs.cloudflare.com/ajax/libs/fullcalendar/3.1.0/fullcalendar.min.css" rel="stylesheet" />


<h2>Calendario</h2>
<div id='calendar' style="width:100%"></div>

<script>
        $(document).ready(function () {
            $('#calendar').fullcallendar({
                header: {
                    left: 'prev,next,Hoje',
                    center: 'title',
                    right: 'month,agendaweek,agendaday'
                },
                defaultview: 'agendaday',
                editable: true,
                alldayslot: false,
                selectable: true,
                slotminutes: 15,
            });
        });
 </script>

Whenever I run, I get the following message:

  

Uncaught TypeError: $ (...). fullcallendar is not a function

Can anyone help me? I do not know if any files are missing to map, or if I'm using some wrong library.
