切换按钮不适用于 AngularJS 和 Angular ui Bootstrap

切换按钮出现，但不起作用。我现在在网上也有相同的代码，但它不起作用，但在 Plunker 中它可以工作。

Plunker - 切换按钮正在工作 http://plnkr.co/edit/R5F5D1FGyHiv9X1cfOoa?p=preview

在线相同的代码 - 按钮不起作用 http://www.kielikosmos.fi/

代码是：

<div class="navbar navbar-inverse navbar-fixed-top" role="navigation">
        <div class="container">
            <div class="navbar-header">
                <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
                    <span class="sr-only">Toggle navigation</span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                </button>

                <div class="nalogo-wrapper">
                    <img class="img-responsive" src="http://placehold.it/50x50&text=Logo" />
                </div>
            </div>
            <div class="collapse navbar-collapse">
                <ul class="nav navbar-nav">
                    <li><a href="#/view1"><span class="glyphicon glyphicon-home"></span> Etusivu</a></li>
                    <li><a href="#/view2">Palvelut</a></li>
                    <li><a href="#/view3">Yhteistiedot</a></li>
                </ul>
            </div><!--/.nav-collapse -->
        </div>
    </div>
    <div id="main">
        <div ng-view>
        </div>
    </div>

我刚刚从一个使用 angular-ui bootstrap 的工作项目中复制了这个：

<div class="navbar navbar-inverse navbar-fixed-top" role="navigation">
    <div class="container">
        <div class="navbar-header">
            <button type="button" class="navbar-toggle btn navbar-btn" ng-init="navCollapsed = true"
                    ng-click="navCollapsed = !navCollapsed">
                <span class="sr-only">Toggle navigation</span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
            </button>
            <a class="navbar-brand" href="/#">Bake-Off</a>
        </div>
        <div collapse="navCollapsed" class="navbar-collapse collapse navbar-responsive-collapse">
            <ul class="nav navbar-nav">
                <li><a href="#" >Link 1</a></li>
                <li><a href="#" >Link 2</a></li>
                <li></li>
            </ul>
            <div class="container navbar-form navbar-right">

            </div>
        </div>
        <!--/.navbar-collapse -->
    </div>
</div>
