jQuery ajax callback problem
<p>I've been using ajax functions like $.post() using jQuery 1.3.2 and was successfull till today, when I switched to v1.4.2 after downloading jquery UI (jquery-ui-1.8.5.custom.min.js)
for using jQuery UI's radio buttons (<code>$( "#radio" ).buttonset();</code>), which wasn't working with the my version (it said <code>.buttonset()</code>is not defined).<br>
After switching to the new version, it seems the callback in <code>$.post</code> is not working. The call is made (i see response in firebug)<br>
Can somebody tell me what is wrong and how to fix it? Please tell me if more information is needed. I haven't added any code as I think it's not a coding error.<br>
Thanks<br><br>
EDIT<br>
This is my code...<br></p>

<pre><code>&lt;script language="javascript" src="jquery-1.4.2.js"&gt;&lt;/script&gt;
&lt;script language="javascript" src="jquery-ui-1.8.5.custom.min.js"&gt;&lt;/script&gt;
&lt;/head&gt;

&lt;body&gt;
&lt;script&gt;
function get() {
    $.post("php.php",{arg:"post"},
           function (data) {
               alert(data);
           });
}
&lt;/script&gt;
&lt;input type="button" value="Click" onclick="get()" /&gt;
</code></pre>

<p>and php:</p>

<pre><code>&lt;?php
    if ( $_SERVER['REQUEST_METHOD'] == 'POST') {
        die('post');
    } else {
        die('get');
    }
?&gt;
</code></pre>
