How to reset Google recaptcha with react-google-recaptcha

Question

Looks like the google recaptcha works in such a way that if a verification attempt has been made with a particular token, it cannot be used again.

Docs states that "you will need to call grecaptcha.reset() to ask the end user to verify with reCAPTCHA again"

I'm trying to attempt this using the react-google-recaptcha npm package.

Here is my code:

function onChange(grecaptcha) {
  console.log(grecaptcha);
  grecaptcha.reset(); // this doesn't work
}

class Captcha extends React.Component {
  render() {
    return <div>
      <Recaptcha
          sitekey='#'
          onChange={onChange(this)}
      /> </div> 
  }
}

When I tried to do the server side validations using the google api https://www.google.com/recaptcha/api/siteverify with response and secret value, the success response always evaluates to "false" after the first validation. To prevent this I'm resetting the grecaptcha as suggested in the docs but it doesn't work.

Anything that I'm missing?

Thanks in advance

EDIT:

https://github.com/dozoisch/react-google-recaptcha offers the reset() utility function which is what I'm trying to call after the user solves the captcha, wondering if I'm not calling it the right way.

Well, this is just a bonus or a more elaborate way of all the above. I am using react-google-recaptcha so this is reactJS and not until I saw this that I found a way to solve the reset issue. It's rather straight forward. Am just explaining to mostly newbies like I think I am on how to do it just as pointed out by @sarneeh, @Chris and @AdityaSrivast

Here's my code snippet.

Captcha.js

import React from "react";
import ReCAPTCHA from "react-google-recaptcha";


const CaptchaVerify = ({yourprops}) => {

 let captcha;

 const onChange = (value) => {
    console.log(value);      
 }

 const setCaptchaRef = (ref) => {
    if (ref) {
      return captcha = ref;
    }
 };

 const resetCaptcha = () => {
   // maybe set it till after is submitted
   captcha.reset();
 }

 return (
   <ReCAPTCHA
     ref={(r) => setCaptchaRef(r) }
     sitekey={process.env.REACT_APP_V2_CAPTCHA_SITE_KEY}
     onChange={onChange, () => resetCaptcha()}
     theme="light"
   />
  )
 };

export default CaptchaVerify;
