Facebook SDK and rails 4 Turbolinks

I'm having a hard time trying to load fast the javascript Facebook SDK into my rails 4 application. Is there a good way to make it work correctly with turbolinks?

if i add this code on my JS application assets. It's not working properly due to turbolinks:

<div id="fb-root"></div>
<script>
  window.fbAsyncInit = function() {
    // init the FB JS SDK
    FB.init({
      appId      : 'YOUR_APP_ID',                        // App ID from the app dashboard
      channelUrl : '//WWW.YOUR_DOMAIN.COM/channel.html', // Channel file for x-domain comms
      status     : true,                                 // Check Facebook Login status
      xfbml      : true                                  // Look for social plugins on the page
    });

    // Additional initialization code such as adding Event Listeners goes here
  };

  // 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/all.js";
     fjs.parentNode.insertBefore(js, fjs);
   }(document, 'script', 'facebook-jssdk'));
</script>

thanks

Quoting this answer

If you prefer to use native Turbolinks 5 events, you can add this script to your Rails assets:

// FacebookSDK
// https://developers.facebook.com/docs/plugins/page-plugin/
(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/ja_JP/sdk.js#xfbml=1&version=v2.8";
  fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk')); // Replace 'facebook-jssdk' with your page id.

// Compatibility with Turbolinks 5
(function($) {
  var fbRoot;

  function saveFacebookRoot() {
    if ($('#fb-root').length) {
      fbRoot = $('#fb-root').detach();
    }
  };

  function restoreFacebookRoot() {
    if (fbRoot != null) {
      if ($('#fb-root').length) {
        $('#fb-root').replaceWith(fbRoot);
      } else {
        $('body').append(fbRoot);
      }
    }

    if (typeof FB !== "undefined" && FB !== null) { // Instance of FacebookSDK
      FB.XFBML.parse();
    }
  };

  document.addEventListener('turbolinks:request-start', saveFacebookRoot)
  document.addEventListener('turbolinks:load', restoreFacebookRoot)
}(jQuery));

I followed the solution suggested by @gallonallen with some small modification. just created a file called turbo.js with following content:

$(document).on('turbolinks:load', function() {

    FB.init({ status: true, cookie: true, xfbml: true });

});

And added //= require turbo in application.js before //= require query and it started working for me. I am using rails 4.2.6 and ruby 2.3.1 with turbo links 5. For me, prior to fix, turbo links was working on my local but not when deployed to staging or prod.

If you're putting your Facebook JS code at the end of your view, use flush in your controller action to ensure it's fully reloaded properly with Turbolinks:

def show
  # ...
  render :show, flush: true
end

Worked like a charm.

I was having a problem with the Like Box not loading when I navigate between pages using turbo links. My solution was to create a social.js.coffee in my assets/javascripts folder. In this file it simply has 

$(document).on 'page:change', ->
  FB.init({ status: true, cookie: true, xfbml: true });

I know its a lot to put in it's own file ;-), but the idea was that I know google analytics, twitter, and others will have the same conflicts and this will be a nice place to house those solutions as well.
