bootstrap modal not working :(

_modal_action.html.erb

<div class="modal-header">
  <!-- modal body & stuff goes here -->
</div>

controller.rb

def modal_action
  respond_to do |format|
    format.html
    format.js
  end
end

link_for_modal.html.erb

<%= link_to "My Modal", modal_action_path, remote: true, 'data-target' => "#modal-window" %>
<!-- hidden div for modal -->
<div id="modal-window" class="modal hide fade" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true"></div>

modal_action.js.erb

$("#modal-window").html("<%= j render("modal_action") %>");
$("#modal-window").modal('show');

I don't see a <div class="modal-dialog"> or a <div class="modal-content"> anywhere in your HTML. Could that be the problem?

Which bootstrap version do you use?
