How to add Connectors programmatically

I'd like to add nodes and connectors programmatically with a UserHandle.
On the OnUserHandleMouseDown event i have created a new node that relates
to the selected node and also added a connector. But the connector is not shown.

Btw: This works on the OnInitialized() without any problem.

        public async void OnApplyShortcut(UserHandleEventsArgs args)
            var selectedNode = this.Diagram.SelectedItems.Nodes.FirstOrDefault();
            if (selectedNode == null) return;

            var relatedNode = new DiagramNode();

            var connector = new DiagramConnector();
            connector.SourceID = selectedNode.Id;
            connector.TargetID = relatedNode.Id;
