"ReCAPTCHA has already been rendered in this element"

[Miguel Diganchi]

Hello people!

I am using the google recaptcha 2. When I render the recaptcha (the first time), after the following  function, 

function renderRecaptcha(container) {


 // get container
 var recaptcha_container = container ? container : $('.rc.m');
 if ($(recaptcha_container).length < 0) {
    console.log('rendering error');
    return false;
 }


 // load recaptcha element taking only first element
 recaptcha_container = $(recaptcha_container)[0];


 // get recaptcha id
 var recaptcha_container_id = $(recaptcha_container).attr('id')
 if (!recaptcha_container_id) {
   console.log('rendering error');
   return false;
 }


 // clear recaptcha container
 $(recaptcha_container).html('');


 // render
 var widget_id = grecaptcha.render(recaptcha_container_id, {
      'sitekey' : '[sitekey]',
    });


 grecaptcha.reset();

}

...the recaptcha is rendering perfectly. But, in the second (and the following) render call to the same element, I am getting this error: 

"ReCAPTCHA has already been rendered in this element" in the rendering context, 

Can you help me with this issue?

Regards!
