title: Rails 4 - datetimepicker-rails gem, datepicker not disabling
body: <p>I am using the datetimepicker-rails gem (<a href="https://github.com/zpaulovics/datetimepicker-rails" rel="nofollow">https://github.com/zpaulovics/datetimepicker-rails</a>) </p>
  
  <p>I would like to have a simple timepicker, but datepicker is always present.
  I tried with using the "format" option, the "pickDate: false" option but it is still there.
  What am I doing wrong?</p>
  
  <p>Here is the sample of my view:</p>
  
  <pre><code>&lt;%= simple_form_for(@hour, html: {class: 'form-inline'}, remote: true) do |f| %&gt;
  &lt;%= f.error_notification %&gt;
  &lt;div class="row form-inputs"&gt;
    &lt;%= f.input :start_time, as: :time_picker, autocomplete: :off %&gt;
    &lt;%= f.input :end_time, as: :time_picker, autocomplete: :off  %&gt;
  &lt;/div&gt;
  &lt;div class="form-buttons"&gt;
    &lt;%= f.button :submit, "Zapisz", class: "btn btn-primary" %&gt;
    &lt;%= link_to '&lt;button type="button" class="btn btn-primary" title="Wstecz"&gt;Wstecz&lt;/button&gt;'.html_safe, hours_path %&gt;
  &lt;/div&gt;
  &lt;% end %&gt;
  </code></pre>
  
  <p>and in coffee script I have </p>
  
  <pre><code>$(document).ready -&gt; $('.time_picker').datetimepicker XXX
  </code></pre>
  
  <p>where XXX was one of the options I tried: <code>format: "H:i"</code>, <code>format: "LT"</code> or <code>pickDate:false</code>.</p>
  
  <p>Thank you in advance for your help.</p>
  
  <p>Regards,
  Paulina</p>
