addEventListener to ClassFactory?

[Kenwio]

I would like to add an eventlistener to var1 here directly, without having to create a new component/class..

var var1:ClassFactory = new ClassFactory( TextInput );
var1.properties = { width : 200, width : 300};
dataGridCol.itemRenderer = var1;Reason being that I would like the itemRenderer to be in the same file as the rest of the DataGrid..

Is this possible somehow??
