title: Sencha Touch: Buttons
body: <p>I am trying to implement buttons in a pop-up window with Sencha Touch 2. 
  How do the buttons work? I would like one button to close the window and another to call the doSomething function.</p>
  
  <pre><code>function foo(){
      Ext.Viewport.add({
          xtype: 'panel',
          scrollable: true,
          centered: true,
          width: 400,
          height: 300,
          items:[
              {
                  docked: 'bottom',
                  xtype: 'titlebar',
                  items:[
                      {
                          xtype: 'button',
                          ui: 'normal',
                          text: 'Do Something',
                          go: 'testsecond'
                      },  
                      {
                          xtype: 'button',
                          ui: 'normal',
                          text: 'Close',
                          go: 'testsecond',               
                      },                  
                  ]
              },
          ]
      });//Ext.Viewport.add
  }
  
  function doSomething() {
      console.log('hi');
  }
