Problem with CellRendererToggle

[strobon]

hello everybody...have trouble with pygtk and glade.
iam working on a simple form with purpose to explain simple ubuntu command
like (gnome-terminal,nautilus,gedit) to newbie user. Might be easier if i attached
the form...

the cellrenderertext is working properly (when i click every row it should explain
the description in textview in right panel).But the cellrenderertoggle is the problem,
i really dont know what to do with it (when row terminal is toggled to true,and
execute button is clicked,then it will open gnome-terminal,which i believe is
"subprocess.call(["gnome-terminal","args"],shell=True)").

!/usr/bin/env python

import gtk.glade
import pygtk
pygtk.require("2.0")

class Basic():
def on_window1_destroy(self, widget, data=None):
gtk.main_quit()

s = treev.get_selection()
(ls, iter) = s.get_selected()
#data0 = ls.get_value(iter, 0)
data1 = ls.get_value(iter, 1)
if data1=="open gnome-terminal":
self.tview.get_buffer().set_text("This is the description for gnome-terminal")
else:
pass
if data1=="open nautilus":
self.tview.get_buffer().set_text("This is the description for nautilus")
else:
pass

    t.set_property("activatable", True)

    q.add_attribute(t, "active", 0)
    t.connect("toggled", self.event_toggle, self.list)

    self.treev.insert_column_with_attributes(-1, "List", r, text=1)
    #pack
    self.treev.set_model(self.list)
    builder.connect_signals(self)   

if name == "main":
wer = Basic()
wer.win.show()
gtk.main()
