When I click on this button a wx.dialog open.
However on my new windows there are two button "Valider" and "Annuler", can you tell me why they don't work, I didn't pass to fix my problem can you help please...
My program:

 
import wx
import wx.lib.buttons as buttons
 
class FenetrePrincipal(wx.Frame):
    def __init__(self, parent, ID, title):
        wx.Frame.__init__(self, parent, ID, title, wx.DefaultPosition, wx.Size(482, 68), style= wx.FRAME_NO_TASKBAR | wx.STAY_ON_TOP )
 
        #Option Button
        bmpOption = wx.Bitmap('btn_option.png',wx.BITMAP_TYPE_PNG)
        self.btnOption = buttons.GenBitmapButton(self, -1, bmpOption, pos = (2,24),size= (18,18), style=wx.BORDER_NONE)
        self.btnOption.SetToolTipString("Options")
        self.Bind(wx.EVT_BUTTON, self.OnFenetreOptions, self.btnOption)
 
        #Options Windows
        self.fen = wx.Dialog( None, -1 , "Options", size=(250, 200), style=wx.DEFAULT_DIALOG_STYLE | wx.DIALOG_MODAL)
 
        label = wx.StaticText(self.fen, -1, "Pseudo :", (20,20))
        self.pseudo = wx.TextCtrl(self.fen, -1, "", size=(110,-1), pos=(100,20))
 
        label = wx.StaticText(self.fen, -1, "Mot de passe :", (20,45))
        self.pwd = wx.TextCtrl(self.fen, -1,"", size=(110,-1), pos=(100,45),  style=wx.TE_PASSWORD)
 
        label = wx.StaticText(self.fen, -1, "Lancement automatique :", (20,90))
        self.checkbox = wx.CheckBox(self.fen, -1, pos=(150, 90))
 
        btnValider = wx.Button(self.fen, 1001, "Valider", pos=(40,135))
        btnValider.SetDefault()
        btnAnnuler = wx.Button(self.fen, 1002, "Annuler", pos=(130,135))
 
        self.Bind(wx.EVT_BUTTON, self.OnValider,  id = 1001)
        self.Bind(wx.EVT_BUTTON, self.OnAnnuler, id= 1002)
 
 
    def OnFenetreOptions(self,event):
        self.fen.Show()
        event.Skip()
 
    def OnValider(self, event):
        print "Valider"
        self.fen.Destroy()
 
    def OnAnnuler(self, event):
        print "Annuler"
        self.fen.Destroy()
 
class MyApp(wx.App):
    def OnInit(self):
        fen = FenetrePrincipal(None, -1, "Title")
        fen.Show(True)
        self.SetTopWindow(fen)
        return True
 
app = MyApp()
app.MainLoop()

# Bind buttons like this:
        btnValider = wx.Button(self.fen, 1001, "Valider", pos=(40,135))
        btnValider.SetDefault()
        btnAnnuler = wx.Button(self.fen, 1002, "Annuler", pos=(130,135))
 
        btnValider.Bind(wx.EVT_BUTTON, self.OnValider,  id = 1001)
        btnAnnuler.Bind(wx.EVT_BUTTON, self.OnAnnuler, id= 1002)
