this ruby loop doesn't work. do i need to do something to allow ruby to work in js.erb?

_import_form.html.erb

<%= form_tag(import_missions_path, :method => :post, :id => "import-js", :remote => true )  do |f| %>
  <ul>
    <% current_user.folders.find_by_order(1).missions.each do |mission| %>
  	<li> <%= check_box_tag "mission_ids[]", mission.id %>
    <%= mission.id.to_s + ". " + mission.title %> </li>
    <% end %>
  </ul>
    <%= submit_tag "Import ", :class => 'btn btn-primary' %>
<% end %>

_missions_field.html.erb

<div class= "fields">
  <div class ="well mission">
    <div class="mission-head control-group">
      <i class="icon-chevron-down" style="float:left;padding:0 5px"></i>
      <a href="#">
        <h3 class="mission-title span5" style="float:left">Mission Title</h4>
      </a>
      <i class="icon-remove" style="float:right;padding:0 5px;"></i>
      <i class="icon-edit" style="float:right;padding:0 5px;"></i>
    </div> <!-- .mission-head -->

    <div class="row">
      <div class="span6 mission-info">
        <%= f.hidden_field :position, :value => "1" %>
        <div class="control-group">
          <%= f.text_field :title, :class =>'row span6' %>
          <%= f.cktext_area :content, :toolbar => 'MyToolbar', :class => 'row span6', :rows => '5', :placeholder => "What is the first step a learner should do? (e.g. Watch an intro video, read certain article)" %>
        </div>
      </div><!-- .mission-info -->
    </div> 
  </div> <!-- .mission -->
