Question

I am a newbie to symfony 2, so i used the traditionnal way of including bootstrap css and js files, and i faced the problem that the navbar is not working in my twig view, the code is working on a normal php web site. So here is my code
{%block header%}
{{ parent() }}
<div class="navbar navbar-inverse navbar-static-top">
<div class="container">
<button class = "navbar-toggle" data-toggle = "collapse" data-target = ".navbar-collapse">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>

<div class="collapse navbar-collapse">
<ul class="nav navbar-nav navbar-left">
<li><h1>test</h1></li>
<li>Accueil</li>
<li class="dropdown">
<a href = "" class="dropdown-toggle" data-toggle="dropdown">Categories
<i class="caret"></i>
</a>
<ul class="navbar-nav navbar-inverse dropdown-menu">
<li>Marocain</li>
<li>Americain</li>
<li>Egyptien</li>
<li>Indian</li>
</ul>
