QML animation not working

[daljit97]

Hello, I am trying to build a simple listview where if the delegate is clicked, its index is changed (-1). Now, I am using a Qml ListModel and its function move(), it works fine but I want to add animation when the position is changed. I am using the "Behavior on" function, but I don't understand why it is not working.
@import QtQuick 1.1
import com.nokia.symbian 1.1

Page {
id: page
ListModel{
id: listModel

    ListElement{
        name: "Red"
    }
    ListElement{
        name: "Green"
    }
    ListElement{
        name: "Blue"
    }
}
ListView{
    id: listView
    anchors.fill: parent
    interactive: false
    model: listModel
    spacing: 10        
    delegate: Rectangle{
        height: 50
        width: 360
        color: name
        MouseArea{
            anchors.fill: parent
            onClicked:listModel.move(index,index-1,1)
        }
        Behavior on y{
            NumberAnimation {}
        }
    }
}

}

To apply animations related to changes to the model, you should use the transition properties of the ListView.
See "ListView.move":http://qt-project.org/doc/qt-5.1/qtquick/qml-qtquick2-listview.html

That function is available only in Qt 5, I am using Qt 4.7.
