title: ExtJS 6 plugin.rowwidget Get binded record upon row body component creation
body: <p>I have a grid with <a href="http://docs.sencha.com/extjs/6.2.0/classic/Ext.grid.plugin.RowWidget.html" rel="nofollow noreferrer">Ext.grid.plugin.RowWidget</a>. When I expand row I have to load some data via ajax using row record data as request parameters and display loaded data in a row body component.</p>
  
  <p>How I can get row record data upon row body component creation? I've tried <code>initComponent</code> and <code>afterrender</code> listener, but I understand that it is not appropriate place because data is not binded yet. I have to listen for another event or?</p>
