body: <p>How to change text dynamically on Ext.draw.Text element?</p>
  
  <pre><code>this.textLabel = Ext.create "Ext.draw.Text"
          type  : 'text',
          text  : me.curValue,
          font  : '24px Arial',
          width : 100,
          height: 30,
          x : 100 
          y : 120
  </code></pre>
  
  <p>This method doesn't work:</p>
  
  <pre><code>   this.textLabel.setText("new text")
  </code></pre>
  
  <p>How can I do that?</p>
