I have a problem with a listview element and the supply with a c++ AbstractListModel.

If I pass the listmodel via qproperty the list entries are displayed correctly.

If I pass the listmodel via qinvokable, the list is only displayed the first time the page is called up. If I call up the page a second time (regardless of whether with the same or a different listmodel), the list remains empty.

ColumnLayout { anchors.fill: parent;
        ListView { id: listview; Layout.fillWidth: true;  Layout.fillHeight: true;
            DelegateChooser {
                id: items
                role: "r_type"
                DelegateChoice { roleValue: type1; SelectlistDelegateITL { p_height: p_listheight; p_width: list.width; p_index: index; p_column1: r_col1; p_column2: r_col2; p_isHeader: false }}
                DelegateChoice { roleValue: type2; SelectlistDelegateI2TL { p_height: p_listheight; p_width: list.width; p_index: index; p_column1: r_col1; p_column2: r_col2; p_column3: r_col3; p_isHeader: false }}
            }   
            //model: cp_screen.selectlistModelA
            model: cp_screen.getSelectlistModelB()
            //currentIndex: cp_screen.getSelectlistIndex(p_key)
            currentIndex: 0
            header: SelectlistDelegateI2TL { p_height: p_listheight; p_width: list.width; p_index: -1; p_column1: cp_screen.getListHeaderIcon(p_key); p_column2: cp_screen.getListHeaderText(p_key); p_isHeader: true }
            delegate: items
            spacing: p_listspacing
        }
    }

QProperty:

Q_PROPERTY(SelectlistModel* selectlistModelA READ getSelectlistModelA NOTIFY signalSelectlistModelChanged)

SelectlistModel* getSelectlistModelA() { return m_model->selectlistModels.first(); }

QInvokable:

Q_INVOKABLE SelectlistModel* getSelectlistModelB() { return m_model->selectlistModels.first(); }

When trying via QInvokable, there is still the corresponding connection in the view for updating the model

Connections { target: cp_screen; function onSignalSelectlistModelChanged() { listview.model = cp_screen.getSelectlistModelB() } }

GetSelectListModelA and getSelectlistModelB return the identical model

Any idea what going wrong with QInvokable way?
