title: Sencha Touch Charts iteminfo
body: <p>in the sencha touch documentary <a href="http://docs-origin.sencha.com/touch/2.4/2.4.1-apidocs/#!/api/Ext.chart.interactions.ItemInfo" rel="nofollow">http://docs-origin.sencha.com/touch/2.4/2.4.1-apidocs/#!/api/Ext.chart.interactions.ItemInfo</a>, it is described how to handle iteminfo</p>
  
  <pre><code>interactions: [{
      type: 'iteminfo',
      listeners: {
          show: function(me, item, panel) {
              panel.setHtml('Stock Price: $' + item.record.get('price'));
          }
      }
  }]
  </code></pre>
  
  <p>But when I apply this to my chart I get a </p>
  
  <pre><code> Cannot read property 'get' of undefined
  </code></pre>
  
  <p>If I output the item with console.log, I don't get an object...</p>
  
  <pre><code>   &lt;canvas class="x-surface" id="ext-element-614" height="214" width="1062" style="left: 0px; height: 214px; width: 1062px;"&gt;&lt;/canvas&gt;
  </code></pre>
  
  <p>any idea how to get around with this in Sencha Touch 2.4.1 </p>
