Django Captcha Decorator - django

Question

I've used a reCaptcha system created by the simpleisbetterthancomplex.com/ website.
In class-based views, it works perfectly fine, but whenever it comes to built-in libraries like:
from django.contrib.auth import views as auth_views
and functionalities:
auth_views.password_reset
it literally does not work as it should. The process of confirming the code of captcha is not executed at all.
I'm having a following usage of it:
url(r'^password/reset/$', check_recaptcha(auth_views.password_reset), name='password_reset'),
decorators.py:
def check_recaptcha(view_func):
#wraps(view_func)
def _wrapped_view(request, *args, **kwargs):
request.recaptcha_is_valid = None
if request.method == 'POST':
recaptcha_response = request.POST.get('g-recaptcha-response')
url = 'https://www.google.com/recaptcha/api/siteverify'
values = {
'secret': settings.GOOGLE_RECAPTCHA_SECRET_KEY,
'response': recaptcha_response
}
data = urllib.urlencode(values)
req = urllib2.Request(url, data)
response = urllib2.urlopen(req)
result = json.load(response)
if result['success']:
request.recaptcha_is_valid = True
else:
request.recaptcha_is_valid = False
messages.error(request, 'Invalid reCAPTCHA. Please try again.')
print(str('Invalid reCAPTCHA. Please try again.'))
return view_func(request, *args, **kwargs)
return _wrapped_view
