postMessage js at web page (build on Outsystems Env.) does not trigger the InAppBrowserEvents messageCallBack action.
I did follow the example to check the cordova_iab is available and test with example's code.
But the the event block does not have any respond.
I've tried use window.webkit.messageHandlers.cordova_iab.postMessage(JSON.stringify(data)); but not work too.
No error show at web and mobile app. I'm pretty sure the web did call the postMessage function.
