How do I get IAP to work on iOS with Cordova?

I'm using Cordova to build my game for iOS and I'm wondering if there is a cordova plugin I need to install. I'm able to get android working by installing the plugin: https://github.com/maxmoore14/AndroidInAppBilling

But is there one for iOS?

In the runtime.js file for the IAP plugin, if you search for

window["store"][/code:33wppses], its assuming this property/object is set... BUT what should be setting this? 

I'm very lost and I need a solution asap, I would appreciate any help on this. Thanks

May be useful, it has IAP related plugins :
