The problem is that you are passing data_func as part of column/attribute 
definition, while it is expected as cellrenderer definition table.  This 
works for me (slightly reformatted to see the table hierarchy more 
clearly):

gtk.TreeViewColumn {
    title = "Val", {
        gtk.CellRendererText { font = "monospace" },
	{ text = reg_column.Value },
        data_func = function(...)
            print("render", ...)
            return "x"
	end
    },
}

It seems to be missing in the docs, I'll try to add it when I get to it.
