sidebar treeview not opening?

[grimmwerks]

I know there were updates to the AdminLTE - and I see you've made some changes but the release is still 0.24 from 2015; for some reason my treeview is not toggling open at all, and I'm even attempting your example (though it's generating html that's different than what's on the website:

<ul class="sidebar-menu tree" data-widget="tree">
      <%= nav_link root_path do %>
        <i class="fa fa-dashboard"></i> <span>Dashboard</span>
      <% end %>
      <%= treeview_link 'Lots of links here' do %>
        <%= nav_link "#" do %>
          <i class="fa fa-angle-double-right"></i>
          One Way
        <% end %>
        <%= nav_link "#" do %>
          <i class="fa fa-angle-double-right"></i>
          Another
        <% end %>
      <% end %>
   
    </ul>

This is generating this in html:

<ul class="sidebar-menu tree" data-widget="tree">
      <li class="active"><a href="/">
        <i class="fa fa-dashboard"></i> <span>Dashboard</span>
</a></li>      
<li class="treeview"><a href="#"><span>Lots of links here</span><i class="fa pull-right fa-angle-left"></i></a><ul class="treeview-menu">
        <li><a href="#">
          <i class="fa fa-angle-double-right"></i>
          One Way
</a></li>        <li><a href="#">
          <i class="fa fa-angle-double-right"></i>
          Another
</a></li></ul></li>   
    </ul>

However, clicking on the 'Lots of Links here' does NOT toggle open at all. Not sure what's stopping it; will try a small test app with just this gem to see if it functions...
