Checkbox multi-select not working

I'm using the Bootstrap plug-in to do the checkbox multi-select, but for some reason I'm not getting the multi check-boxes.

This is the website I'm using http://davidstutz.de/bootstrap-multiselect/

and this is my code:

<link rel="stylesheet" href="css/bootstrap.min.css" type="text/css"/>
<script type="text/javascript" src="js/jquery.min.js"></script>
<script type="text/javascript" src="js/bootstrap.min.js"></script>

<!-- Include the plugin's CSS and JS: -->
<script type="text/javascript" src="js/bootstrap-multiselect.js"></script>
<link rel="stylesheet" href="css/bootstrap-multiselect.css" type="text/css"/>


@section('content')
<div class='container'>
//rest of code

... ...

<div class="form-group">
            <label for='state'>State</label>
            <select name='state' id='state' multiple='multiple'>
                <option value='CA'>California</option>
                <option value='VA'>Virginia</option>
                <option value='CO'>Colorado</option>
                <option value='IA'>Iowa</option>
                <option value='WA'>Washington</option>
            </select>		
        </div>

... ...

<script type='text/javascript'>
    $(document).ready(function() {
        $('#state').multiselect();
    });
<script>

Any ideas as to why it's not doing the checkboxes?
