I'm  relatively new to sharepoint development. I want to load events from sharepoint list to fullcalendar month view. How can I achieve that with JSOM(not with REST api)? 
So far I can add to the list from the calendar but I can not see the saved item (event) on the calendar when I refresh the page .
 
I apperciate any kind of tips.

Here is the code so far i have tried:

    var items = list.getItems("");

    clientContext.load(items);
    //Execute the Query Asynchronously
    clientContext.executeQueryAsync(onSuccess, onFail);
    function onSuccess() {
    var enumerator = items.getEnumerator();

    for (var i = 0; i < enumerator.length; i++) {
        var currentListItem = enumerator.get_current();
        NewEvents.push({
            ID: enumerator[i].get_id(),
            title: enumerator[i].get_item('task')
        });
    }
    }

    function onFail(sender, args) {
        alert(args.get_message());
    }



    function CalendarSetup() {
    schedulecCalendar = $('#myCalendar').fullCalendar({
        header: {
            left: 'prev,next today',
            center: 'title',
            right: ''
        },
        theme: true,
        defaultView: 'month',
        selectable: true,
        events: NewEvents,
        selectHelper: true,
        height: 500,
        rendering: true,
        select: function (start, end, allDay) {
            $('#txtDate').datepicker("setDate", new Date(start));
            $(".collapse").collapse('show');
        },
        editable: true,

        eventClick: function (calEvent, jsEvent, view) {
            $('#eventTitle').val(calEvent.title);
            $('#calEventDialog #allday').val([calEvent.className == "gbcs-halfday-event" ? "1" : "2"]).prop('checked', true);
            $("#calEventDialog").dialog();

            $("#calEventDialog").dialog("option", "buttons", [
              {
                  text: "Edit",
                  click: function () {
                      calEvent.title = $('#eventTitle').val();
                      $('#myCalendar').fullCalendar('updateEvent', calEvent);
                      $(this).dialog("close");
                  }
              },
            {
                text: "Delete",
                click: function () {
                    $('#myCalendar').fullCalendar('removeEvents', calEvent._id);
                    $(this).dialog("close");
                }
            },
            {
                text: "Cancel",
                click: function () {
                    $(this).dialog("close");
                }
            }
            ]);
            $("#calEventDialog").dialog("option", "title", "Edit Event");
            $('#calEventDialog').dialog('open');
        },
    });
    }


The newEvent array couldn't fetch events from the sharepoint list.
