  <pre><code>    Ext.define('blackbutton.view.Login.Login', {

  id:'loginview',
  requires: [    
    'Ext.field.Password',
    'blackbutton.store.Login.LoginLS'

  config: {
      style: 'background-color:#0B0B0C',
      cls: 'core',
      scrollable: {direction: 'vertical', directionLock: true},
       html      : '&lt;section class="nt_contentWrap"&gt;'+
  
       ' &lt;img src="resources/images/profile_header_signup.jpg" width="320" height="142"  alt=""/&gt; &lt;br&gt;'+
        '&lt;br&gt;'+
          '&lt;span class="title"&gt; Login           &lt;/span&gt; '+
    ' &lt;ul class="ul-na"&gt;'+
            ' &lt;li&gt;&lt;input type="text" placeholder="Email" name="bbid"&gt;&lt;/li&gt;'+
  
            ' &lt;li&gt;'+
    ' &lt;input type="text" placeholder="Password"  maxlength="11" name="bbpassword"&gt;&lt;/li&gt;'+

      listeners : [
          {
              element  : 'element',
              delegate : 'button#sigup',
              tap      : function () {
                  alert('test');
              }
          },
          {
              element  : 'element',
              delegate : 'button#login',
              tap      : function () {
                  alert('login');
              }
          }
  
      ]
      }
  
      });
  </code></pre>
  
  <p>I need to add listener for two button. Which are signup button and login button. The tap event seem like no fire.</p>
  
  <p>However if i add listener for one button only.</p>
  
  <pre><code>listeners : 
  {
      element  : 'element',
      delegate : 'button#sigup',
      tap      : function () {
          alert('test');
      }
  }
  </code></pre>
