addEventListener to ClassFactory?

programming flash
1

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??
