Facebook Like Box not loading on Ember app

I'm trying to get the like box to work inside our ember app, in a template called about. The problem is that if I enter the ember app from another route (instead of about route), then navigate to the about route with link-to helpers, then the like box is not rendered. Instead, if I enter/refresh the about route directly, it renders just fine. Any ideas on how to make it render even if somebody navigates to that route from another route ?

templates/about.hbs:

...
<div class = "fb-like-box" data-href = "http://ift.tt/1Cisg3t" data-width = "250"
                 data-height = "313" data-colorscheme = "light" data-show-faces = "true" data-header = "false"
                 data-stream = "false" data-show-border = "true"></div>
...

views/application.js:

export default Ember.View.extend({

  facebook_app_id: config.APP.facebook_app_id,

  initLibs: function ()
            {
              // initialize Facebook SDK
              var facebook_id = this.facebook_app_id;
              window.fbAsyncInit = function ()
              {
                FB.init({
                  appId:   facebook_id,
                  xfbml:   true,
                  version: 'v2.1'
                });
              };
              (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'));
            }.on('didInsertElement')
});
