Oauth (facebook) in angular2-meteor

Following tutorial of socially (using typescript), i am trying to add oauth ability to my application.
Removed custom and default authentication and added

meteor add service-configuration```
 and added  ```{{>loginButtons}}```,  also tried
```<button id="facebook-login" facebook-login```

neither one is working for me.
For oauth I have referred: 
https://www.codetutorial.io/meteor-accounts-custom-ui-tutorial/

My codebase is here:

Any help or pointers to right direction appreciated.

Thanks
Harish
