Not able to use window.addEventListener method in JSLink javascript

Question

Hi,
I have developed 2 app parts and passing values between them using post message utility of windows. It works fine from script editor web part but fails when I am trying to use it as JSLink.
I am getting window is undefined error message.
I was wondering if I can use window.addEventListener from javascript which is referenced in JSLink property.
Can anyone please help.

Check if below helps
<script language="ecmascript" type="text/ecmascript">
var listItem;
var list;
var clientContext;
function getSetListItem() {
this.clientContext = SP.ClientContext.get_current();
if (this.clientContext != undefined && clientContext != null) {
var webSite = clientContext.get_web();
this.list = webSite.get_lists().getByTitle("Custom");
this.listItem = list.getItemById(3);
clientContext.load(this.listItem);
this.clientContext.executeQueryAsync(Function.createDelegate(this, this.OnLoadSuccess),
Function.createDelegate(this, this.OnLoadFailed));
function OnLoadSuccess(sender, args) {
var value = this.listItem.get_item("SampleOne");
this.listItem.set_item("SampleTwo", value);
this.listItem.update();
this.clientContext.load(this.listItem);
this.clientContext.executeQueryAsync(Function.createDelegate(this, this.OnLoadSuccess1),
Function.createDelegate(this, this.OnLoadFailed));
function OnLoadSuccess1(sender, args) {
alert(this.listItem.get_item("SampleTwo"));
function OnLoadFailed(sender, args) {
alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
}</script>
<input id="btnGetSetListItem" onclick="getSetListItem()" type="button" value="Get & Set List Item" />
function AddCar() {
//Retrieve the txtCar and check if it has some text.
var txtCar = document.getElementById("txtCar");
if (txtCar.value == "") {
alert("please enter a car");
return;
//Retrieve the clientContext
var clientContext = SP.ClientContext.get_current();
//Retrieve the current website
var webSite = clientContext.get_web();
//Retrieve the lists
var lists = webSite.get_lists();
//Get the Cars List
var carsList = lists.getByTitle("Cars");
//Create new IteamCreationInformation
var itemCreationInfo = new SP.ListItemCreationInformation();
//the addItem takes the itemCreationInformation object
//and returns the listItem
var listItem = carsList.addItem(itemCreationInfo);
//Set the title of the list Item
//to the value in the txtCar
listItem.set_item("Title", txtCar.value);
//Call Update the listItem
listItem.update();
//Finally execute the operation
//pass to it a 2 callBack methods OnSucceed and OnFailure
clientContext.executeQueryAsync(
Function.createDelegate(this,this.Succeeded)
,Function.createDelegate(this,this.Failed));
Finally add the 2 CallBack method
function Succeeded() {
alert("Succeeded");
function Failed(sender,args) {
alert("fail");
