zf2和ajax我无法获取参数

Question

我无法从控制器传递数据ajax me有什么解决方案吗？ 按钮单击操作

$(".bajaAlumno").click(function () {
    var urlform = "<?php echo $this->url(null, array('controller'=>'Academius','action'    =>'bajaAlumnos' ) ); ?>";
    var dato= $(this).attr('id');
    var myData = {textData:dato};

    $.ajax({
        type:"POST",
        url:"/Academius/bajaAlumnos",
        data:{data:myData},
        success: function(data){
            //The callback function, that is going to be executed 
            //after the server response. data is the data returned
            //from the server.

            // Show the returned text
            //$("#answer").text(data.text);
            //$("#answer").text(data.text);
            alert('enviado');
        }
    });
});

和控制器

public function bajaAlumnosAction()
{
    die(var_dump($this->params()->fromPost()));   
}

一个答案？
