Django - Post ajax request forbidden 403 with ExtJS - ajax

Question

I am using ExtJs to create a button that do an ajax post to my django application, but the post is blocked by a FORBIDDEN (403) error.
I tryed to pass the CSRF token in as POST data by setting a custom X-CSRFToken header to the value of the CSRF token (https://docs.djangoproject.com/en/1.3/ref/contrib/csrf/#ajax) without success
ExtJS.js
action = new Ext.Button({
text: 'Ajax Test',
handler: function () {
Ext.Ajax.request({
url: 'test/',
method: 'POST',
headers: { 'Content-Type': 'application/json'},
params: {'test': 'test'},
success: function(response, opts) {
var obj = Ext.decode(response.responseText);
console.dir(obj);
},
failure: function(response, opts) {
console.log('server-side failure');
}
});
},
});
view.py
def test(request):
print "TEST WORKING"
print dict(request.POST.copy().iteritems())
return HttpResponse("")

action = new Ext.Button({
text: 'Ajax Test',
handler: function () {
var csrf = Ext.util.Cookies.get('csrftoken');
Ext.Ajax.request({
url: 'test/',
method: 'POST',
headers: { 'Content-Type': 'application/json'},
params: {'test': 'test', 'csrfmiddlewaretoken': csrf},
success: function(response, opts) {
var obj = Ext.decode(response.responseText);
console.dir(obj);
},
failure: function(response, opts) {
console.log('server-side failure');
}
});
},
});

I put this in my Application launch function:
Ext.require(["Ext.util.Cookies", "Ext.Ajax"], function(){
// Add csrf token to every ajax request
var token = Ext.util.Cookies.get('csrftoken');
if(!token){
Ext.Error.raise("Missing csrftoken cookie");
} else {
Ext.Ajax.defaultHeaders = Ext.apply(Ext.Ajax.defaultHeaders || {}, {
'X-CSRFToken': token
});
}
});
