title: extjs5 widgetcolumn multiple widgets in a single cell
body: <p>I create a widgetcolumn as the panel in which several components. How can i link record parameters with these components? </p>
  
  <p>For example:</p>
  
  <pre><code>{
      xtype: 'widgetcolumn',
      dataIndex: 'data',
      widget: {
          xtype: 'panel',
          height: 77,
          width: 642,
          layout: {
              type: 'vbox',
              align: 'stretch'
          },
          items: [
              {
                  xtype: 'button',
                  text: record.get('name')    //&lt;&lt;-- how can i link this record from the grid with this component?
              },
              {
                  xtype: 'button',
                  text: record.get('type')    //&lt;&lt;-- how can i link this record from the grid with this component?
              },
              {
                  xtype: 'button',
                  text: record.get('location')    //&lt;&lt;-- how can i link this record from the grid with this component?
              }
          ]
      }
  }
  </code></pre>
  
  <p>I have a following store:</p>
  
  <pre><code>var store = Ext.create('Ext.data.Store', {
       fields:['name', 'type', 'location'],
       data:[
            {name: 'name1', type: 'type1', location: 'loc1'},
            {name: 'name2', type: 'type2', location: 'loc2'}
       ]
  });
  </code></pre>
  
  <p>Maybe, I can get access to the record via renderer function? Something like this:</p>
  
  <pre><code> renderer: function(value, meta, record) {
      //How can I get access to widget instance?
   }
  </code></pre>
