I trying to make ListView and delete that item.
My Question is why can't i add an item to ListView?

Here is my Code

import QtQuick 2.7
import Ubuntu.Components 1.3
//import QtQuick.Controls 2.2
import QtQuick.Layouts 1.3
import Qt.labs.settings 1.0
import QtQuick.Controls 2.5

MainView {
    id: root
    objectName: 'mainView'
    applicationName: 'lists.lists'
    automaticOrientation: true

    width: units.gu(45)
    height: units.gu(75)

    function addtolistView(){
        listView.append({sender: "First Row Added", title: "Add"})
    }

    ListView {
        id: listView
        anchors.fill: parent
        model: ListModel {
            ListElement { sender: "Bob Bobbleton"; title: "How are you going?" }
            ListElement { sender: "Rug Emporium"; title: "SALE! All rugs MUST go!" }
            ListElement { sender: "Electric Co."; title: "Electricity bill 15/07/2016 overdue" }
            ListElement { sender: "Tips"; title: "Five ways this tip will save your life" }
        }
        delegate: SwipeDelegate {
            id: swipeDelegate
            text: model.sender + " - " + model.title
            width: parent.width



            ListView.onRemove: SequentialAnimation {
                PropertyAction {
                    target: swipeDelegate
                    property: "ListView.delayRemove"
                    value: true
                }
                NumberAnimation {
                    target: swipeDelegate
                    property: "height"
                    to: 0
                    easing.type: Easing.InOutQuad
                }
                PropertyAction {
                    target: swipeDelegate
                    property: "ListView.delayRemove"
                    value: false
                }
            }

            onClicked: {
                swipe.complete=false
            }

            swipe.right: Label {
                id: deleteLabel
                text: qsTr("Delete")
                color: "white"
                verticalAlignment: Label.AlignVCenter
                padding: 12
                height: parent.height
                anchors.right: parent.right

                SwipeDelegate.onClicked: listView.model.remove(index)

                background: Rectangle {
                    color: deleteLabel.SwipeDelegate.pressed ? Qt.darker("tomato", 1.1) : "tomato"
                }
            }
        }
    }

    Button{
        text: "Add"
        onClicked: addtolistView()
    }
}

Got this error here (TypeError: Property 'append' of object QQuickListView(0x124f560) is not a function)

How can that be fixed?

Thanks for your time
