Call checkbox's click event seems erroneous?
$('#my_checkbox').click();

(function($) {
  $.fn.flip = function() {
    this.prop("checked", !this.prop("checked"));
    this.triggerHandler("click");
    this.triggerHandler("change");
  };
})(jQuery);

$('my_checkbox').flip();

(function($) {
  $.fn.flip = function() {
    this.each(function() {
        this.checked = !this.checked;
    });
    this.triggerHandler("click");
    this.triggerHandler("change");
  };
})(jQuery);

$("my_checkbox").click(function() {
    var $this = $(this);
    setTimeout(function() {
        // Actually do something with $this
    }, 0);
});
