Event Move

I've followed the tutorial and added an event handler and set event move handling like so:
EventMoveHandling="CallBack"
OnEventMove="DayPilotCalendar1_EventMove"

but whenever I load the page with the DayPilot Scheduler control it seems that moving an event is still disabled, I get no change of cusor when i mouse over / hold mouse down on an event to move it.

My event handler in VB looks like:

Public Sub DayPilotCalendar1_EventMove(ByVal sender As Object, ByVal e As DayPilot.Web.Ui.Events.EventMoveEventArgs)

dbUpdateEvent(e.Tag("id"), e.NewStart, e.NewEnd, e.NewResource)

DayPilotScheduler1.DataBind()
DayPilotScheduler1.Update()
End Sub

Is there anything else im missing here?

Thanks
