Google reCAPTCHA v2 on Yii1.1.6 not shown

I’m trying to make google reCaptcha on my projects that used Yii 1.1.6.

And I already follow this documentation But my google reCaptcha is not shown.

Anybody can help, please?

This is my loginForm.php models

class LoginForm extends CFormModel
	public $username;
	public $password;
	public $rememberMe;
	public $verifyCode;

	private $_identity;

	 * Declares the validation rules.
	 * The rules state that username and password are required,
	 * and password needs to be authenticated.
	public function rules()
		return array(
			// username and password are required
			array('username, password', 'required'),
			// rememberMe needs to be a boolean
			array('rememberMe', 'boolean'),
			// password needs to be authenticated
			array('password', 'authenticate'),
			array('verifyCode', 'required'),
			array('verifyCode', 'ext.yiiReCaptcha.ReCaptchaValidator'),

	 * Declares attribute labels.
	public function attributeLabels()
		return array(
			'username' => 'Email',
			'password' => 'Password',
			'verifyCode' => 'Verification Code',
			'rememberMe' => 'Remember me',

and this is my login view

<div class="form-group has-feedback">
          $this->widget('ext.yiiReCaptcha.ReCaptcha', array(
            'model'     => $model,
            'attribute' => 'verifyCode',

also, I already changed the main.php on protected/config

'components' => array(
		'reCaptcha' => array(
			'name' => 'reCaptcha',
			'class' => 'ext.yiiReCaptcha.ReCaptcha',
			'key' => 'my-key-in-here',
			'secret' => 'my-key-in-here',

Please, anybody can solve this?
Thank you before.

At the last, I use a stupid way to solve this issue.
So I add this code
<script src="" async defer></script> on above of form.
And using this code
<div class="g-recaptcha" data-sitekey="6LddDZgbAAAAAArLBzXYH0RQ7MMExsp4fbmNVhNf"></div>
to render the captcha.

And it worked!
