title: Laravel 5.5 Invisible Recaptcha not submitting form
body: <p>I have a project in Laravel 5.5 and trying to implement Google Invisible Captcha but it keeps giving me this error on console:</p>
  
  <pre><code>Uncaught TypeError: _captchaForm.submit is not a function
  </code></pre>
  
  <p>The package I'm using is this one <a href="https://github.com/albertcht/invisible-recaptcha" rel="nofollow noreferrer">enter link description here</a></p>
  
  <p>The error is only on the js script, I already tried removing all js from the site for just this to show but neither way works.</p>
  
  <p>I have a basic form </p>
  
  <pre><code>&lt;form action="{{ route('post-contact') }}" method="post"&gt;
                  {{ csrf_field() }}
                  &lt;div class="form-group"&gt;
                      &lt;label&gt;Nombre:&lt;/label&gt;
                      &lt;input type="text" class="form-control" placeholder="Nombre" name="name" /&gt;
                  &lt;/div&gt;
                  &lt;div class="form-group"&gt;
                      &lt;label&gt;Email:&lt;/label&gt;
                      &lt;input type="email" class="form-control" placeholder="Email" name="email" /&gt;
                  &lt;/div&gt;
                  &lt;div class="form-group"&gt;
                      &lt;label&gt;Mensaje:&lt;/label&gt;
                      &lt;textarea class="form-control height-120" placeholder="Mensaje" name="msg"&gt;&lt;/textarea&gt;
                  &lt;/div&gt;
                  @captcha('en')
                  &lt;div class="form-group"&gt;
                      &lt;button class="btn theme-btn" name="submit" type="submit"&gt;Enviar consulta&lt;/button&gt;
                  &lt;/div&gt;
              &lt;/form&gt;
  </code></pre>
  
  <p>I already enable debug on the console and it says that everything is binded as it should:</p>
  
  <pre><code>Checking element binding of _submitForm...
  true
  Checking element binding of _captchaForm...
  true
  Checking element binding of _captchaSubmit...
  true
  </code></pre>
  
  <p>Any help will be appreciated, this is driving me nuts since yesterday.</p>
  
  <p>Thanks</p>
