Unity Social Plugin IOS - Facebook Events not getting generated

Hi, I'm currently working on the facebook plugin for IOS and looks like the facebook events are not getting triggered. To test this out, I had put the debug logs inside the static block for FacebookBinding() in FacebookBinding.cs

// on login, set the access token FacebookManager.preLoginSucceededEvent += () => { Debug.Log( "preLoginSucceededEvent" ); Facebook.instance.accessToken = getAccessToken(); };

The above logs are not getting printed in case of a successful login. Please let me know if I am missing something here or there is some additional configuration required for this (on top of prime31 plugin documentation)

Thanks.
