JQuery .post function dataType parameter seems not to do anything
<p>Using JQuery version 1.4.4, I am unable to get a proper JSON output when I call .ajax or .post like the following:</p>

<pre><code>$.ajax({type: "POST", url: callbackUri, data: { cow: ["oh", "hello", "there"]}, success: returnFunction, dataType: "json"});
</code></pre>

<p>or the following:</p>

<pre><code>$.post(callbackUri, { cow: ["oh", "hello", "there"]}, returnFunction, "json");.
</code></pre>

<p>The body of the HTTP request looks like this in both cases:</p>

<pre><code>cow%5B%5D=oh&amp;cow%5B%5D=hello&amp;cow%5B%5D=there
</code></pre>

<p>It's probably a very simple configuration issue. Any help is appreciated!</p>
