Enable/Disable using Radio is not working
<p>I am trying to disable/enable dropdown box based on user selection of radio buttons. I have the following JSFiddle: <a href="http://jsfiddle.net/QekRS/" rel="nofollow"><strong>JSFiddle</strong></a> which works fine on it's own.</p>

<pre><code>$('input[type=radio]').click(function() {
    var r_id = $("input[@name=sc]:checked").attr('id');
    alert(r_id);

    if (r_id == "bName") {
        //enable By Name drop down
        $(".dName").prop('disabled', false);
        //disable By Specialty drop down
        $(".dSpecialty").prop('disabled', true);
    }
    if (r_id == "bSpecialty") {
        //enable By Specialty drop down
        $(".dSpecialty").prop('disabled', false);
        //disable By Name drop down
        $(".dName").prop('disabled', true);
    }
});
</code></pre>

<p>The same exact code in the following page is not working: <a href="http://www.interfaithmedical.com/chosen/example.jquery.html" rel="nofollow"><strong>Website Demo</strong></a></p>
