A hacky solution is below. It's just to point out that the state (text 
input) should be stored outside the delegates, as people are mentioning 
- in this case, it's stored in textArray.

import QtQuick 2.2
import QtQuick.Controls 1.2

ApplicationWindow {
     id: applicationWindow1
     visible: true
     width: 200
     height: 200
     title: qsTr("TextEdit on ListView Test")


     property var textArray: {
         var a = [];
         for (var i = 0; i < listView1.count; ++i) {
             a[i] = "";
         }
         a;
     }

     ListView {
         id: listView1
         x: 286
         width: 110
         boundsBehavior: Flickable.StopAtBounds
         anchors.horizontalCenter: parent.horizontalCenter
         anchors.bottomMargin: 0
         anchors.topMargin: 0
         anchors.bottom: parent.bottom
         anchors.top: parent.top
         clip: true

         model: ListModel {
             ListElement {
                 name: "Grey"
                 colorCode: "grey"
                 text: ""
             }

             ListElement {
                 name: "Red"
                 colorCode: "red"
                 text: ""
             }

             ListElement {
                 name: "Blue"
                 colorCode: "blue"
                 text: ""
             }

             ListElement {
                 name: "Green"
                 colorCode: "green"
                 text: ""
             }
             ListElement {
                 name: "Grey"
                 colorCode: "grey"
                 text: ""
             }

             ListElement {
                 name: "Red"
                 colorCode: "red"
                 text: ""
             }

             ListElement {
                 name: "Blue"
                 colorCode: "blue"
                 text: ""
             }

             ListElement {
                 name: "Green"
                 colorCode: "green"
                 text: ""
             }
             ListElement {
                 name: "Grey"
                 colorCode: "grey"
                 text: ""
             }

             ListElement {
                 name: "Green"
                 colorCode: "green"
                 text: ""
