使用jQuery ajax的隐形ReCaptcha

Question

<form id="myForm" >
    <input type="email" name="email" /><br />
    <input type="password" name="password" /><br/>
    <!--<input type="submit" value="log in" />-->
    <button class="g-recaptcha" data-sitekey="6LdK..." data-callback="onSubmit">log in</button>
</form>
<div id="status"></div>

<script>

    function onSubmit(token){
        document.getElementById("myForm").submit();
    }

    $(document).ready(function(){

        $("#myForm").submit(function(event){
            event.preventDefault();
            var datas = $("#myForm").serialize();
            $.ajax({
                type: "POST",
                url: "test.php",
                data: datas,
                dataType: "json",
                    beforeSend: function(){
                        $("#status").html("logging in...");
                    },
                    success: function(response){
                        $("#status").html(response.text);
                        if(response.type=="success"){
                            window.location.replace("/myaccount");
                        }
                    },
                    error: function(){
                        $("#status").html("Failed.");
                    }
            });
        });

    });
</script>

ReCaptcha需要设置一个“data-callback”，我不知道如何将它与我已经存在的“.submit（function（event）”函数绑定。
我的“onsubmit（）”技巧不起作用，它忽略了“Ajax”并刷新页面。

如何在我的“datas”变量中发送“g-recaptcha-response”值以将其发布到test.php？
