Why not simply create a ClassFactory for your itemRenderer instead? You
won't require to extend datagrid and just need to create a custom
ItemRenderer.
gridColumn itemRenderer="{customItemRendererFactory}"
being customItemRendererFactory
cf= new ClassFactory(SomeCustomItemRenderer)
cf.properties ={ test: "someValue};
customItemRendererFactory = cf;
