Ionic workflow questions and facebook authentication issue

I'm trying to implement mobile application using Ionic. I'm following this, but unfortunately logging in doesn't work on real device. It works fine in the browser and the emulator. I did every step from the tutorial, I did the tutorial 2-3 times and still get the same error.

I am logged in successfully on my device but then I see the following screen: enter image description here

I already have both urls as redirect urls in my application settings in FB.

http://localhost:5000/oauthcallback.html
https://www.facebook.com/connect/login_success.html

I tried to debug OpenFB with alerts. I can see "cordova events" alert but then I have alerts on the first lines of loginWindow_loadStartHandler and loginWindow_exitHandler but they are not executed. I guess that the problem is there but I have no idea how to fix it.

if (runningInCordova) {
  alert("cordova events");
  loginWindow.addEventListener('loadstart', loginWindow_loadStartHandler);
  loginWindow.addEventListener('exit', loginWindow_exitHandler);
}

Also I have some questions about Ionic and Phonegap.

I use Ubuntu and I am trying to build iOS and Android applications. My application's structure is:

app/
 hooks/
 platforms/
 plugins/
 scss/
 www/

Also I have InAppBrowser plugin:

cordova plugin add org.apache.cordova.inappbrowser

but this plugin is not part of app/www folder.

I am trying to build a phonegap application in their site. I made a .rar file of the app/www folder content and upload it. Everything seems to be fine. But in Phonegap site when I click PLUGINS, I see This application has no plugins. How should I add inappbrowser to the application, maybe that is the reason why my FB authentication doesn't work. If I build the whole app folder, again I see the same message - This application has no plugins.

So when create an archive file of the content for Phonegap, which folder I should archive - the whole app folder with all subfolders or only app/www? What is the correct flow? Also how crossplatform app should now about added plugins?
