title: Form submission blocked by bootstrapValidator
body: <p>I have a problem when I try to submit a form which uses bootstrapValidator() for validating fields -> it doesn't submit, php file is not executed (I know that because I've tried without booststrapValidator and it works).
  Any idea?</p>
  
  <p>Form looks like this:</p>
  
  <pre><code>&lt;form id="contactForm"  class="form-horizontal" role="form" action="contact_form.php" method="post"&gt;
        &lt;div class="form-group"&gt;
          &lt;label class="control-label col-sm-2" for="name"&gt;Name&lt;/label&gt;
          &lt;div class="col-sm-10"&gt;
            &lt;input type="text" class="form-control" id="name" name="name" placeholder="Name"&gt;
          &lt;/div&gt;
        &lt;/div&gt;
        &lt;div class="form-group"&gt;
          &lt;label class="control-label col-sm-2" for="email"&gt;Email&lt;/label&gt;
          &lt;div class="col-sm-10"&gt; 
            &lt;input type="email" class="form-control" id="email" name="email" placeholder="example@domain.com"&gt;
          &lt;/div&gt;
        &lt;/div&gt;
        &lt;div class="form-group"&gt; 
          &lt;label class="control-label col-sm-2" for="msg"&gt;Mesage&lt;/label&gt;
          &lt;div class="col-sm-10"&gt; 
              &lt;textarea class="form-control col-sm-10" id="msg" name="msg" placeholder=""&gt;&lt;/textarea&gt;
          &lt;/div&gt;
        &lt;/div&gt;
        &lt;div class="form-group"&gt;
          &lt;label id="captchaOperation" class="control-label col-sm-2" for="captcha"&gt;&lt;/label&gt;
          &lt;div class="col-sm-10"&gt; 
            &lt;input type="text" class="form-control" id="captcha" name="captcha" placeholder="Answer"&gt;
          &lt;/div&gt;
        &lt;/div&gt;
        &lt;div class="form-group"&gt; 
          &lt;div class="col-sm-offset-2 col-sm-10"&gt;
            &lt;input type="submit" class="btn btn-primary" id="submit" name="submit" value="Send"&gt;&lt;/button&gt;
          &lt;/div&gt;
        &lt;/div&gt;
  &lt;/form&gt;
