How to add multiple invisible recaptcha on one page?

I added two invisible recaptcha elements, but when I saw the code in the inspect element, only one invisible recaptcha was added to my page. My code is:

 <div id="captcha1" class="g-recaptcha"
      data-sitekey="your_site_key"
      data-callback="onSubmit"
      data-size="invisible"></div>
<div id="captcha2" class="g-recaptcha"
      data-sitekey="your_site_key"
      data-callback="onSubmit"
     ></div>

Get link from Programmatically call recaptcha

Can you help me what I'm doing wrong?

Below, a more reliable solution for Peter and Alessandro responds with nesting elements.

<script>
$(".g-recaptcha").each(function() {
    var object = $(this);
    grecaptcha.render(object.attr("id"), {
        "sitekey" : "6LdwRC0UAAAAAK0hjA8O4y1tViGPk9ypXEH_LU22",
        "callback" : function(token) {
            object.parents('form').find(".g-recaptcha-response").val(token);
            object.parents('form').submit();
        }
    });
});
</script>

<form>
    <input type="text" name="example"/>
    <button id="captcha1" class="g-recaptcha">submit form 1</button>
</form>

<form>
    <input type="text" name="example"/>
    <button id="captcha2" class="g-recaptcha">submit form 2</button>
</form>

There was the same problem. After some perplexity, I got him to work.

<script type="text/javascript">
    var onloadCallback = function() {
        $(".g-recaptcha").each(function() {
            var el = $(this);
            grecaptcha.render($(el).attr("id"), {
                "sitekey" : SITE_KEY,
                "callback" : function(token) {
                    $(el).parent().find(".g-recaptcha-response").val(token);
                    $(el).parent().submit();
                }
            });
        });
    };
