ZF2, ZF2-NoCaptcha, FormValidation

I'm using szmnmichalowski/ZF2-NoCaptcha for captcha verifications and I have following setup. How do I use Identical validator to validate 'captcha' form element with 'g-recaptcha-response' generated and embedded to form on the fly? I get 'The two given tokens do not match' error message even I type correct captcha. But I can validate it with a custom Validator.

composer.json

{
    "require": {
        "php": ">=5.3.3",
        "zendframework/zendframework": "2.3.3",
        "spoonx/sxmail": "1.4.*",
        "slm/queue": "0.4.*",
        "szmnmichalowski/zf2-nocaptcha": "dev-master"
    }
}

config/application.config.php

return array(
    'modules' => array(
        'SxMail',
        'SlmQueue',
        'Application',
        'NoCaptcha'
    )
);
