Dynamic Bootstrap dropdown in Angular is not working

Question

I'm trying to create a Bootstrap navbar with dropdowns from a two-level array. However, the dropdowns will only work when the dropdown class on <li> and the dropdown-toggle class on <li> are hard-coded.

Since some of my menu items should have a dropdown, and some should not, I want to set these using ng-class. Is there any way to delay ui-bootstrap untill the html has been compiled?

I found somewhere that jQuery('.dropdown-toggle').dropdown(); might reinitialize the dropdown, but the dropdown() function is not recognized in my case.

<div class="navbar-collapse collapse">
    <ul class="nav navbar-nav">
        <li ng-repeat="navItem in structure.navItems" ng-class="{'active': structure.isActive(navItem), 'dropdown': navItem.subItems}"> <a href="{{navItem.href}}" ng-class="{'dropdown-toggle': navItem.subItems}" data-toggle="dropdown">
              {{navItem.name}}
              <span class="caret" ng-if="navItem.subItems"></span>
            </a>

            <!-- start dropdown menu -->
            <ul class="dropdown-menu">
                <li ng-repeat="subItem in navItem.subItems"> <a href="{{subItem.href}}" ng-class="{'active': structure.isActive(subItem)}">
                  {{subItem.name}}
                </a>

                </li>
                <!-- dit kan ook nog: <li class="divider"></li>
              <li class="dropdown-header">Nav header</li>
              -->
            </ul>
            <!-- end dropdown menu -->
        </li>
    </ul>
</div>

I have managed to get it working based on the solution from various posts. The trick is that you use ui-bootstrap's option dropdown-append-to-body (something with rendering DOM) and that you use ng-if before applying other parameters like above. Disclaimer: the dropdown is not as smooth as the twiter's bootstrap but it's working.
