Django/AJAX/JQuery - Unable to receive a POST response

Ok, first of all, I'm a JQuery/AJAX noob, but I can manage to get around most of the time.

Here's the problem.

For some reason everytime I use POST as the AJAX type I don't get a response, but when I use GET I do get a response.

Why is this happening and how do I fix it.

HTML

<form action="/trivia/ajax_test/" method="post" onsubmit="return ajaxTest()">
{% csrf_token %}
<button type="submit">AJAX</button>
</form>

JQuery/AJAX

function ajaxTest() { 
    $.ajax({
        type: 'POST', // Works with 'GET', but failing with 'POST'
        url: '/trivia/ajax_test/',
        data: {some_text: 'The test is working'},
        success: function(result){alert(result);} 
    });

    return false;
}

URLS

(r'^trivia/ajax_test/$', 'findadownload.trivia.views.ajax_test'),

VIEWS

def ajax_test(request):
    if request.is_ajax():
        return HttpResponse("Success")

    else:
        result = "You went to the url directly"

    return HttpResponse(result)

This is because of the CSRF protection built into Django.

Add this to your Javascript, before your Ajax call or disable CSRF protection for your POST view.

function getCookie(name) {
    var cookieValue = null;
    if (document.cookie && document.cookie != '') {
        var cookies = document.cookie.split(';');
        for (var i = 0; i < cookies.length; i++) {
            var cookie = jQuery.trim(cookies[i]);
            // Does this cookie string begin with the name we want?
            if (cookie.substring(0, name.length + 1) == (name + '=')) {
                cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
                break;
            }
        }
    }
    return cookieValue;
}

var csrftoken = getCookie('csrftoken');

function csrfSafeMethod(method) {
    // these HTTP methods do not require CSRF protection
    return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
}
$.ajaxSetup({
    crossDomain: false, // obviates need for sameOrigin test
    beforeSend: function(xhr, settings) {
        if (!csrfSafeMethod(settings.type)) {
            xhr.setRequestHeader("X-CSRFToken", csrftoken);
        }
    }
});
