Insert Events into the database by FullCalendar

I would like to know if there is any way I can insert some event into the database by FullCalendar ,

I've got the current version and I saw that it has a function that it shows a prompt for me to type the event title, but it's only in js so if I update the page it does not leave the event registered.

How can I do this? Follow the code below

$(document).ready(function() {
        var currentLangCode = 'pt-br';

        // build the language selector's options
        $.each($.fullCalendar.langs, function(langCode) {
            $('#lang-selector').append(
                $('<option/>')
                    .attr('value', langCode)
                    .prop('selected', langCode == currentLangCode)
                    .text(langCode)
            );
        });

        // rerender the calendar when the selected option changes
        $('#lang-selector').on('change', function() {
            if (this.value) {
                currentLangCode = this.value;
                $('#calendar').fullCalendar('destroy');
                renderCalendar();
            }
        });

        function renderCalendar() {
            $('#calendar').fullCalendar({
                header: {
                    left: 'prev,next today',
                    center: 'title',
                    right: 'month,agendaWeek,agendaDay'
                },
                defaultDate: Date(),
                selectable: true,
                selectHelper: true,
                select: function(start, end) {
                    var title = prompt('Event Title:');
                    var eventData;
                    if (title) {
                        eventData = {
                            title: title,
                            start: start,
                            end: end
                        };
                        $('#calendar').fullCalendar('renderEvent', eventData, true); // stick? = true
                    }
                    $('#calendar').fullCalendar('unselect');
                },
                eventClick: function(event) {
                    $(this).popover({html:true,title:event.title,placement:'top',container:'body',content: 'vamo ver se vai agora'}).popover();
                },
                lang: currentLangCode,
                buttonIcons: false, // show the prev/next text
                weekNumbers: true,
                editable: false,
                eventLimit: true, // allow "more" link when too many events
                events: {
                    url: 'fullcalendar/demos/php/get-events.php',
                },
                loading: function(bool) {
                    $('#loading').toggle(bool);
                }
            });
        }

        renderCalendar();
    });
