title: python class on html button click
body: <p>I'm totally new to all this python things, I've searched on my problem but withiout results, so I count on your help guys :)</p>
  
  <p>I have a template file with button:</p>
  
  <pre><code>&lt;button class="btn" value="{{invoice.number}}"&gt;Send&lt;/button&gt;
  </code></pre>
  
  <p>In different file I have a class which runs function from another file:</p>
  
  <pre><code>class ReminderManual(webapp2.RequestHandler):
  ...
      for inv in invoices:
          is_send = reminder.send(inv)
  </code></pre>
  
  <p><br>And I'd like to:</p>
  
  <ol>
  <li><p>run this class when the button is pushed</p></li>
  <li><p>display is_send value</p></li>
  </ol>
  
  <p><br>Any ideas how I can do that?</p>
