Bootstrap Dropdown is not working - angularjs

Question

I've added the dropdown in the header.html which i included in the index.html of an angular app.
<ul class="nav navbar-nav navbar-right">
<li class="dropdown profile hidden-xs">
<a class="dropdown-toggle" data-toggle="dropdown">
<span class="meta">
<span class="text">{{slUserObj.username}}</span>
<span class="caret"></span>
</span>
</a>
<ul class="dropdown-menu animated flipInX" role="menu">
<li>
<a href="javascript:void(0);" ng-click="showProfile();main.page='profile'">
<span class="icon"><i class="fa fa-user"></i>
</span>My Account</a>
</li>
<li>
<a href="javascript:void(0);" ng-click="showProfile();main.page='profile'">
<span class="icon"><i class="fa fa-user"></i>
</span>Carreir Details</a>
</li>
<!--<li>
<a href="javascript:void(0);">
<span class="icon"><i class="fa fa-envelope"></i>
</span>Messages</a>
</li>
<li>
<a href="javascript:void(0);">
<span class="icon"><i class="fa fa-cog"></i>
</span>Settings</a>
</li>-->
<li class="divider"></li>
<li>
<a href="javascript:void(0);" ng-click="logout()">
<span class="icon"><i class="fa fa-sign-out"></i>
</span>Logout</a>
</li>
</ul>
</li>
here is the index.html
<section id="main-wrapper" class="theme-default">
<!-- Page wrapper -->
<header id="header" ng-include="'views/header.html'" ng-show="isAuthenticated"></header>
<!-- Left Sidebar Navigation -->
<aside class="sidebar sidebar-left" ng-include="'views/left-sidebar.html'" ng-show="isAuthenticated"></aside>
<!-- Content wraper -->
<section class="main-content-wrapper" ng-class="{'main-content-wrapper':isAuthenticated,'main-content-wrapper-full':!isAuthenticated}">
<!-- Main content view -->
<div ui-view></div>
<!-- Footer -->
<div ng-include="'views/footer.html'"></div>
</section>
<!-- /Content wraper-->
Now the dropdown in the header.html is not working once unhiding the header block after login, but its working when i'm refreshing the page after login.
