Cordova - Windows8 does not recognise navigator.notification.alert - windows-8

Question

I am having a hard time getting cordova to work as I expect.
Here are the steps I have taken.
npm install -g cordova
md apps
cd apps
cordova create win8 com.win8.tryout win8tryout
cordova platform add windows8
In the www/js folder I edited the index.js adding
navigator.notification.alert('try me out');
to the device ready event.
Then I build the cordova project from the apps/win8 folder
cordova build
Then I opened the visual studio solution in the platforms/windows8 folder and ran the application.
The code fails at the navigator.notification.alert('try me out'); line with
"JavaScript runtime error: Unable to get property 'alert' of undefined or null reference"
I suspect that the build process isn't working correctly because the cordova.js file in the windows8/www directory is only 52kb and I was expecting a file of about 300kb.
Any ideas or suggestions would be appreciated.

Ok so a bit more research and I realised my sort comings.
From the documentation here:
"From version 3.0 onward, Cordova implements all device APIs as plugins..."
I had originally downloaded v2.9.1 which did not implement the plugin architecture.
