Please make sure that you don't specify the [events] attribute in the template:
<daypilot-scheduler [config]="config" #scheduler></daypilot-scheduler>
If you specify the [events] attribute it will override the directly-loaded events on the next change detection:
<daypilot-scheduler [config]="config" [events]="events" #scheduler></daypilot-scheduler>
Let me know if it didn't help.
