Prevent Double Posts Does not work

[chobo2]

Hi

I am using jquery 1.7.1 and ajax manager 3.12 and I can't get the preventDoubbleRequests to work.

I have

$.manageAjax.create('Test', { preventDoubbleRequests: true, cacheResponse: false });

      $.manageAjax.add('Test',
            {
                type: 'Post',
                data: frm,
                url: "URL',
                success: function (response)
                {

                }
            });

Yet I spam as many times as I want and it will keep posting. I asked someone else to try it as well and they get the same problem. Can you verify if I am doing anything wrong?

Thanks
