title: Bootstrap form validation not not working on set of number fields for date
body: <p>I have these three fields for date:</p>
  
  <pre><code>&lt;div class="col-xs-12 form-group col-sm-6"&gt;
    &lt;div class="row"&gt;
      &lt;div class="col-xs-3"&gt;
        &lt;input autocomplete="off" class="form-control birth-day" id="dan_rodjenja" name="dan_rodjenja" max="31" min="1" placeholder="DD" required type="number" value="" /&gt;
      &lt;/div&gt;
      &lt;div class="col-xs-3"&gt;
        &lt;input autocomplete="off" class="form-control birth-month" id="mjesec_rodjenja" max="12" min="1" name="mjesec_rodjenja" placeholder="MM" required type="number" value="" /&gt;
      &lt;/div&gt;
      &lt;div class="col-xs-6"&gt;
        &lt;input autocomplete="off" class="form-control birth-year" id="godina_rodjenja" max="2000" min="1910" name="godina_rodjenja" placeholder="GGGG" required type="number" value="" /&gt;
      &lt;/div&gt;
   &lt;/div&gt;  
  </code></pre>
  
  <p>For example, if the first and second fields are filled and the third one is empty, I get no errors (no red borders). Or when I leave the first field empty, all three show errors. Could someone help me with this?</p>
