Matias,

I think the problem is that you are expecting your items to retail the
typed text instead of your model.  I think the ListView destroys delegates
that are not within the view.  Since your model is not retaining the typed
text, this would explain why it is going away.  I modified your delegate to
show that this is the problem.

delegate: Item {
    width: 100
    height: 40

    Component.onDestruction: {
        console.debug("Item destroyed")
    }

    Rectangle {
        width: 100
        height: 40
        color: colorCode
        TextEdit {

            font.pointSize: 23
            anchors.fill: parent

            font.bold: true
            anchors.verticalCenter: parent.verticalCenter
        }
    }
}
