        title: 'Become my Buddie'
    },
    function (response) {
        if (response && response.request_ids) {
            //if sucess do something
            //How many people did the user invited?
            var $howManyInvites = String(requests).split(',').length;
        } else {
            //  alert('canceled');
            return false;
