UI5 composite control binding

I have created a new control that is supposed to be an umbrella for a button and when you click on it, a MessagePopover is shown.

Hence my control has an aggregation called items which is forwarded using the "forwarding:" clause to the MessagePopover. My problem is, the button should show the "getItems().length" item count as text and I can't find a working solution for that.

text: "{= ${items}.length } ????"

See example here:

Your code is very close, you're just missing the slash

text: "{= ${/items}.length } ????"
