body: <p>using this

  <p>demo here:
  <a href="http://jonthornton.github.com/jquery-timepicker/" rel="nofollow">http://jonthornton.github.com/jquery-timepicker/</a></p>
  
  <p>on a rails 3.2 app</p>
  
  <p>trying to use the datepair example
  and cant seem to figure out why the time fields don't work
  the calendar for the first field pops up, but nothing else.</p>
  
  <p>view code:</p>
  
  <pre><code>  %p.datepair{'data-language' =&gt; "javascript"}
      = f.text_field :starttime, :class =&gt; 'date start'  
      %span.ui-timepicker-container
        = f.text_field :starttime, :class =&gt; 'time start ui-timepicker-input', :autocomplete =&gt; "off", :value =&gt; "12:15am"  
        %ul.ui-timepicker-list{ :tabindex =&gt; "-1", :style =&gt; "position: absolute; left: 567.667px; z-index: 2; top: 2246.87px; display: none;" }
          %li 12:00am
          %li 12:15am
          ...
          %li 12:30am
          %li 1:00am
      %span.ui.timepicker-container
        = f.text_field :starttime, :class =&gt; 'time start ui-timepicker-input', :autocomplete =&gt; "off"  
        %ul.ui-timepicker-list.ui-timepicker-with-duration{ :tabindex =&gt; "-1", :style =&gt; "position: absolute; left: 674.5px; z-index: 2; top: 2422.87px; display: none;"}
        = f.text_field :starttime, :class =&gt; 'date start hasDatePicker'  
  </code></pre>
  
  <p>in the firebug console I get:</p>
  
  <pre><code>$this.timepicker is not a function
  
  $this.timepicker(opts);
  </code></pre>
