This is the solution I used to get login callback. You can add this code for your Facebook login button in your render method:

Login

In your code, add these lines:

componentDidMount: function() {
    // facebook signin  button render
    window.fbAsyncInit = function() {
      FB.init({
        appId      : 'replace with your app id here',
        cookie     : true,  // enable cookies to allow the server to access
        // the session
        xfbml      : true,  // parse social plugins on this page
        version    : 'v2.1' // use version 2.1
      });

      // login callback implementation goes inside the function() { ... } block
      FB.Event.subscribe('auth.statusChange', function(response) {
        // example implementation
        if (response.authResponse) {
          console.log('Welcome!  Fetching your information.... ');
          FB.api('/me', function(response) {
            console.log('Good to see you, ' + response.name + '.');
          });
        } else {
          console.log('User cancelled login or did not fully authorize.');
        }
      });
    }.bind(this);

    // Load the SDK asynchronously
    (function(d, s, id) {
      var js, fjs = d.getElementsByTagName(s)[0];
      if (d.getElementById(id)) return;
      js = d.createElement(s); js.id = id;
      js.src = "//connect.facebook.net/en_US/sdk.js";
      fjs.parentNode.insertBefore(js, fjs);
    }(document, 'script', 'facebook-jssdk'));
  }
}

Calling FB.Event.subscribe('auth.statusChange', callback_function) during component initialization is important because that's basically your login callback. Checkout here for FB.Event documentation.
