Custom content of Fullcalendar event after eventResize - fullcalendar

Question

I try to set dynamically the content of a FullCalendar event after the user would have resized it but I can't figure out how to achieve this, since both eventResize and eventResizeStop don't get the element in their callback.
I have also tried to modify the event in eventResizeStop and to get the value in eventRender (since I noticed that a rerender is called after resize stop) but this ain't work because still get the "old" event content.
Any idea how to achieve this?
$('#calendar').fullCalendar({
eventRender: function (event, element) {
console.log(event.something); // still same value
},
eventResizeStop: function (event, jsEvent, ui, view) {
event.something = 'try to push a new value'; // no effect
$(this).find('.fc-title').replaceWith('something'); // no effect
},
eventResize: function (event, delta, revertFunc, jsEvent, ui, view) {
$(this).find('.fc-title').replaceWith('something'); // no effect
}
});
Mockup of what I would like to achieve:
before user modification:
-----------------
| event content |
-------v---------
after user modification of the length/duration of the event:
-----------------
| event content |
| is now not the|
| same anymore |
-------v---------

I've found the solution. Modifying the event in eventResize is effectively the right way but after doing so, the event should be updated in the calendar respectively an update should be explicitly called
$('#calendar').fullCalendar({
eventRender: function (event, element) {
console.log(event.something);
},
eventResize: function (event, delta, revertFunc, jsEvent, ui, view) {
event.something = 'my new value';
$("#calendar").fullCalendar('updateEvent', event);
}
});
