How to refresh list

Hi,
could you please advise me, how to reload/fresh list of dependent supplements displayed in opened parent entity?
The main entity id ApplicationForm, then it has 1:N Supplements.
The Suplements are displayed in a table.
I have a use-case, when I create the Supplements in the background in the controller, but the new ones are not displayed in the table. Refresh “Action” butotn does not work
… After reopening the form, they are displyed correctly.
So how do I refresh the UI table with the list of Supplements?
Thank you.

@OnDelete(DeletePolicy.CASCADE)
    @Composition
    @OrderBy("createdDate DESC")
    @OneToMany(mappedBy = "applicationForm")
    private List<Supplements> supplements;
ApplicationForm e = getEditedEntity();
List<Supplements> supplements = e.getSupplements();
if (supplements == null) {
  supplements = new ArrayList<>();
  e.setSupplements(supplements);
}
s = dataManager.create(Supplements.class);
s.setApplicationForm(e);
s.setXxxxx...
s.setYyy...

s = dataContext.merge(s);

You should add items to the collection container linked to the UI table.
Use supplementsDc.getMutableItems().add(...) as shown in the example in the docs.
