Django: fullcalendar drag events and save - django

Question

I 'm trying to drag the events and store them in the database with getJSON
javascript file :
<script type='text/javascript'>
function saveMyData(event, dayDelta, minuteDelta) {
$.getJSON("{% url events_drag %}", {'title': event.title, 'start': event.start,
'end': event.end}, function(data) {
});
}
</script>
<script type='text/javascript'>
$(document).ready(function() {
$('#eventFilterCalendar').fullCalendar({
eventDrop: function(event, dayDelta, minuteDelta) {
saveMyData(event);
},
eventResize: function (event, dayDelta, minuteDelta) {
saveMyData(event);
},
</script>
views :
def eventsdrag(request):
print 'events...'
untitre= request.GET['title']
unstart= request.GET['start']
unend= request.GET['end']
print 'untitre', untitre
print 'unstart', unstart
print 'unend', unend
Event.title = untitre
Event.start = unstart
Event.end = unend
Event.save()
event_list = []
event_list.append({
...
'start': Event.start,
'end': Event.end,
'title': Event.title,
})
return http.HttpResponse(json.dumps(event_list),
content_type='application/json')
model :
class Event(models.Model):
title = models.CharField(_(u"Nom de l'étude"), max_length=100)
start = models.DateTimeField(_(u"début"))
end = models.DateTimeField(_('fin'))
the function eventdrag should read event.title, event.start, event.end and save them in the database
but request.GET don't work..I display 'events..' and nothing else..
