Titanium: WebView using Navigation Bar

Question

I'm using Titanium. I am trying to show web page with navigation bar.

I want to put Back button at the top left position inside navigation bar which works as browser's back.

Below is my current code.

Could anybody help me with this??

Thanks in advance.

 var w = Titanium.UI.createWindow({  
    backgroundColor:'#fff',
    leftNavButtonLabel:'back',});
var navGroup = Ti.UI.iPhone.createNavigationGroup({
  window:w
});

var backBtn = Titanium.UI.createButton({
      title:'Back',
   style:Titanium.UI.iPhone.SystemButtonStyle.BORDERED
});

var webView = Titanium.UI.createWebView({
    url : 'http://gooogle.com',
    canGoBack : true,
});

backBtn.addEventListener( 'click', function() {
    webview.goBack();
});

w.add.setLeftNavButton(backBtn);

w.add(webView);

w.add(navGroup);

w.open();

w.navGroup.open();

Try, This... or

var main_win = Ti.UI.createWindow({
});

var w = Titanium.UI.createWindow({  
    backgroundColor:'#fff',
    leftNavButtonLabel:'back',

});
var navGroup = Ti.UI.iPhone.createNavigationGroup({
  window:w
});

var backBtn = Titanium.UI.createButton({
      title:'Back',
   style:Titanium.UI.iPhone.SystemButtonStyle.BORDERED
});

var webView = Titanium.UI.createWebView({
    url : 'http://gooogle.com',
    canGoBack : true,
});

backBtn.addEventListener( 'click', function() {
    webview.goBack();// Goes back one entry in the web view's history list. to the previous page.

});

w.add.setLeftNavButton(backBtn);

w.add(webView);

main_win.add(navGroup);

main_win.open();

for Navigation new window


         navGroup.open(Window name);

for Closing last open window;

         navGroup.close(Window name);
