Answer 1

Finally i found the answer, implement the listview ontriggered function like below

onTriggered: {
                        if(indexPath!=0){
                        var selectedItem = dataModel.data(indexPath);
                        var newPage = nextPage.createObject();
                        navigationPane.push(newPage);
                    }
