you're stringifying a renderer object and putting that into the renderer
hash key. what you likely need to do there is 
        renderer => 'Gtk2::CellRendererToggle',
see examples/simplelist.pl in the Gtk2 source. you shouldn't be creating
a renderer to pass into add column. you should be telling it what kind
of renderer to use when it gets that type of column. perhaps it should
be renderer_type, but the documentation does explain that it is a type
string, not an actual renderer.

there isn't a method Gtk2::SimpleList::get_column. that method is on the
parent class Gtk2::TreeView and is doced as it should be on it's page.

from SimpleList.pm list of column types:
        'bool'   => {type=>'Glib::Boolean', 
the column type in there appears to be 'bool' not boolean.  in fact the
default 'bool' column type uses
        renderer =>  Gtk2::CellRendererToggle
as i suggested above.
