title: Bootstrap tour template not applying id on all buttons
body: <p>I added an id to the next button to style it following the template tag in bootstrap tour. I applied a new id to the next button but it only applies it to the first one, not the latter stages. Does anyone know why?</p>
  
  <pre><code>template: "&lt;div class='popover tour'&gt;
  &lt;div class='arrow'&gt;&lt;/div&gt;
  &lt;h3 class='popover-title'&gt;&lt;/h3&gt;
  &lt;div class='popover-content'&gt;&lt;/div&gt;
  &lt;div class='popover-navigation'&gt;
      &lt;button class='btn btn-default' data-role='prev'&gt;« Prev&lt;/button&gt;
      &lt;span data-role='separator'&gt;|&lt;/span&gt;
      &lt;button class='btn btn-default' id="thisone" data-role='next'&gt;Next »&lt;/button&gt;
  &lt;/div&gt;
  &lt;button class='btn btn-default' data-role='end'&gt;End tour&lt;/button&gt;
  &lt;/nav&gt;
  &lt;/div&gt;",
  </code></pre>
