Sub Menu Creation

Question

Dear All,
Please see below the source code. It is working fine, but I want to add one sub menu in "Window" or in any default menu supported by InDesign.
var myMe = app.menus.item("$ID/Main").submenus.add("Test");
myMe.remove();
var mySSA= app.scriptMenuActions.add("123");
var mySSM = app.menus.item("$ID/Main").submenus.add("Test");
var myEL = mySSA.eventListeners.add("onInvoke", function(){
      subs();
function subs()
      alert("Selction is: ",  "Test");
var mySSM = mySSM.menuItems.add(mySSA);
Regards,
Rajeev

Modified from the javascript examples:
#targetengine "session"
//MakeScriptMenuAction.jsx
//An InDesign CS3 JavaScript
//Adds a menu at the end of the main menu bar.
var mySampleScriptAction = app.scriptMenuActions.add("Display Alert");
var myEventListener = mySampleScriptAction.eventListeners.add("onInvoke", myFunction, false);
//If the submenu "Script Menu Action" does not already exist, create it.
//You might have to force InDesign to redraw the menu (by switching
//out of the application and back again) to make the menu item appear.
try{
    var mySampleScriptMenu = app.menus.item("$ID/Main").submenus.item("Window").submenus.item("Script Menu Action");
    mySampleScriptMenu.title;
catch (myError){
    var mySampleScriptMenu = app.menus.item("$ID/Main").submenus.item("Window").submenus.add("Script Menu Action");
var mySampleScriptMenuItem = mySampleScriptMenu.menuItems.add(mySampleScriptAction);
function myFunction(){
    alert("This menu item was added by a script.");
And to clean up again:
#targetengine "session"
app.scriptMenuActions.everyItem().remove();
try{
    var mySampleScriptMenu = app.menus.item("$ID/Main").submenus.item("Window").submenus.item("Script Menu Action");
    mySampleScriptMenu.remove();
catch (myError){
    alert("Could not remove menu");
