Calendar example update not firing

[Dmoney]

I'm trying to convert the calendar example to use a remote store. I got rid of the MemoryEventStore and replaced

     this.eventStore = Ext.create('Ext.calendar.data.MemoryEventStore', {
            data: Ext.calendar.data.Events.getData()
        });

with

     this.eventStore = Ext.create('Ext.calendar.data.EventStore');

my store looks like this:

Ext.define('Ext.calendar.data.EventStore', {    extend: 'Ext.data.Store',
    model: 'Ext.calendar.data.EventModel',
    autoLoad: true,
    remoteSort:true,
    proxy: {
        type: 'ajax',
        api: {
        read: 'data/jsonEvents.php',
        update: 'data/updateEvents.php',
       create: 'data/addEvent.php',
       destroy: 'data/deleteEvent.php'
    },
        reader: {
            type: 'json',
            root: 'eventDatabase',
            successProperty: 'success',
             totalProperty: 'totalRecords'
        }
    }
});

Adding an event works and deleting an event works but editing an event never calls data/updateEvents.php. nothing happens when I drag an event or when I edit an event from the event form.

How do I update an event?

I still can't get the update to work in the calendar example. has anyone got this working with a remote store? the add and delete work but the update doesn't seem to do anything. the update function is called. but the commit never calls my php script.

Any ideas?
