title: Adding slider to Rails application
body: <p>I am having trouble adding a simple slider to my rails 3 application.  There don't seem to be any errors in my JavaScript:</p>
  
  <p>My Gemfile has:</p>
  
  <pre><code>gem 'jquery-rails'
  
  group :assets do
    gem 'jquery-ui-rails'
  end
  </code></pre>
  
  <p>skills.js.coffee:</p>
  
  <pre><code>jQuery -&gt;
    $('#slider').slider
  </code></pre>
  
  <p>skills/show.html.erb:</p>
  
  <pre><code>&lt;div id="slider"&gt;&lt;/div&gt;
  </code></pre>
  
  <p>application.js</p>
  
  <pre><code>//= require jquery
  //= require jquery_ujs
  //= require jquery-ui
  //= require bootstrap
  //= require_tree .
  </code></pre>
  
  <p>It does not show up in my application.  Are there any other steps which I need to take to make it show up?  </p>
  
  <p>Thanks</p>
