Add captcha action to your controller, add captcha to your form, add field and validate rules for captcha to your model. Read more here.

And add button in view for update captcha image, like this:

<?php echo $form->field($model, 'captcha')->widget(Captcha::className(), [
    'imageOptions' => [
        'id' => 'my-captcha-image'
    ]
]); ?>

<?php echo Html::button('Refresh captcha', ['id' => 'refresh-captcha']);?>
<?php $this->registerJs("
    $('#refresh-captcha').on('click', function(e){
        e.preventDefault();

        $('#my-captcha-image').yiiCaptcha('refresh');
    })
"); ?>
