Jquery发布数据3次

jQuery(document).ready(function () {
    $("div").bind('click', $.proxy(function (event) {
        var id = $(event.target).attr('id');
        var go = jQuery.isNumeric(id);
        if (go) {
            $.post("favswrite.php", {
                id: id
            });
            alert('Formül '+id+' favorilerinize eklendi !');
        }
    }, this));
});

This code is post data 3 times. Where is wrong and loop it ? I want post data 1 times.
