Bootstrap - dropdown menu not working?

My dropdown menu in Bootstrap doesnt appear to be working - can anyone alert me to the problem? Right now it displays the dropdown, but clicking it does nothing. Thanks!

JS:

$(document).ready( function() {
$('.dropdown-toggle').dropdown();
});

HTML:

<div class="navbar navbar-fixed-top">
    <div class="navbar-inner">
        <div class="container" style="width: auto;">

            <a class="brand" style="text-indent: 3em" href="#">
                Title
            </a>

            <ul class="nav">
                <li><a href="#">Profile</a></li>
                <li class="active"><a href="#">Statistics</a></li>
                <li><a href="#">Reader</a></li>

                <li class="dropdown" id="menu1">
                    <a class="dropdown-toggle" data-toggle="dropdown" href="#menu1">
                    Options
                    <b class="caret"></b>
                    </a>
                    <ul class="dropdown-menu">
                        <li><a href="#">Action</a></li>
                        <li><a href="#">Another action</a></li>
                        <li><a href="#">Something else here</a></li>
                        <li class="divider"></li>
                        <li><a href="#">Separated link</a></li>
                    </ul>
                </li>

            </ul>

Check if you're referencing jquery.js BEFORE bootstrap.js and bootstrap.js is loaded only once. That fixed the same error for me:

<script type="text/javascript" src="js/jquery-1.8.0.js"></script>
<script type="text/javascript" src="js/bootstrap.min.js"></script>

This is a Rails specific answer, but I had this same problem with Bootstrap dropdown menus in my Rails app. What fixed it was adding this to app/assets/javascripts/application.js:

//= require bootstrap

Hope that helps someone.

putting

<script src="js/bootstrap.min.js"></script>    

file at the last after the

<script src="jq/jquery-2.1.1.min.js"></script>  solved this problem for me .

this is how i use write it now and no problem

<script src="jq/jquery-2.1.1.min.js"></script>
<script src="js/bootstrap.min.js"></script>

I had to download the source files instead of just the compressed files that it says to use for quick start on the bootstrap website
