ID of an event (Fullcalendar)

Question

I need add an id to every single event from Fullcalendar, I found this http://arshaw.com/fullcalendar/docs/event_data/Event_Object/ but I don't know how, this id is
unique for every single event, because then I save the events in a Mysql database. Thanks

Clear Solution is

When you fetch events with Ajax also assign "id" that coming from DB

id:entry.id

$.ajax({ 
    url: '/eventsJson', 
    type: 'GET', 
    data: { }, 
    error: function() {
        alert('there was an error while fetching events!');
    } 
}).done(function (doc) { 

    var event = Array();
    $.each(doc, function(i, entry) {
        event.push({id:entry.id, title: entry.title, start: entry.start});
    });

Event Click

eventClick: function(event, jsEvent, view) {
               var title = prompt('Event Title:', event.title, { buttons: { Ok: true, Cancel: false} });

           if (title){
           event.title = title;

           var data = {
                'title':title
            };

           $.ajax({
             url: '/events/'+event.id,
             data: data,
             type: 'POST',
             dataType: 'json',
             success: function(response){
               if(response.status == 'success')
               $('#calendar').fullCalendar('updateEvent',event);
             },
             error: function(e){
               alert('Error processing your request: '+e.responseText);
             }
           });
           }
        }
