Assist with a small fix on cordova plugin (JAVA / JS)

I have made a Cordova java plugin that is 99% working with Ionic, the only issue is I need to pass the payment success back to the web view so that the JavaScript callback can see it. This is a 100% personal project, I have a very small budget as I know the right Java / Cordova developer will know how to do this. I am not a fluent Java or Cordova dev, hence why I need assistance. My budget is $10, do not bid any higher. You will be sent a link to my public GitHub repo, where you can fork and fix the code. You will be added in the [login to view URL] if you can help me out. Please reply "CorDo0va" at the top of your proposal, if you don't I won't reply or consider you. Payment will be sent upon the fix, not before.
