javascript - Bootstrap drowpdown not working in Meteor -

folks. i'm working on meteor application , have following section in navigation template meant render dynamically built dropdown menu.

for reason, it's not dropping down, , have no idea why.

i'm using twbs:boostrap package provide bootstrap.

template section:

<ul class="nav navbar-nav">     <li class="dropdown">         <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">browse <span class="caret"></span></a>         <ul class="dropdown-menu" role="menu">             {{#each categories}}                 <li><a href="{{pathfor 'browse' slug=this.slug}}">{{name}}</a></li>             {{/each}}         </ul>     </li> </ul> 

categories helper:

template.registerhelper('categories', function() {     return categories.find(); }); 

when inspect dom on page, menu there, , followed documentation on bootstrap's website make sure have right, have no idea i'm doing wrong. paths being generated correctly iron router (pathfor).

any appreciated.
