AJAX request not working until after hard refresh (Treebook)

I've just finished the using AJAX badge for adding a friend on Treebook. All the Ruby stuff is working fine, as is the AJAX, but only after a hard page refresh.

When I press the 'add friend' button, it doesn't acknowledge the javascript at all and the click takes me to a new page. After refreshing the profile page, the javascript/AJAX kicks in and the button works as expected.

The Javascript is below (it's the same as Jason uses in the video).

Is there a setting in rails / something I can do in javascript to ensure the script loads with the page?

$(document).ready(function() {
  $('#add-friendship').click(function(event) {
    event.preventDefault();
    var addFriendshipBtn = $(this);
    $.ajax({
      url: Routes.user_friendships_path({user_friendship: { friend_id: addFriendshipBtn.data('friendId') }}),
      dataType: 'json',
      type: 'POST',
      success: function(e) {
        addFriendshipBtn.hide();
        $('#friend-status').html("<a href='#' class='btn btn-success'>Friendship Requested</a>");
      }
    });
  });
});

You can wrap the whole thing in a 

$(document).ready(function() {
});

but I'm guessing that won't fix it quite so easily.

did you do //= require js-routes as well at top of your application.js?
