    Angry Sort items in UltimateListCtrl

    I want to create an ultimate list ctrl based table where the user can sort the columns by clicking on the column header. Here's the code I attempted:

    Code:
    import wx
    import wx.lib.mixins.listctrl as listmix
    from wx.lib.agw import ultimatelistctrl as ULC
    
    APPNAME='Sortable Ultimate List Ctrl'
    APPVERSION='1.0'
    MAIN_WIDTH=300
    MAIN_HEIGHT=300
     
    musicdata = {
    0 : ("Bad English", "The Price Of Love"),
    1 : ("DNA featuring Suzanne Vega", "Tom's Diner"),
    2 : ("George Michael", "Praying For Time"),
    3 : ("Gloria Estefan", "Here We Are"),
    4 : ("Linda Ronstadt", "Don't Know Much"),
    5 : ("Michael Bolton", "How Am I Supposed To Live Without You"),
    6 : ("Paul Young", "Oh Girl"),
    }

    class TestUltimateListCtrlPanel(wx.Panel, listmix.ColumnSorterMixin):
     
        #----------------------------------------------------------------------
        def __init__(self, parent):
            wx.Panel.__init__(self, parent, -1, style=wx.WANTS_CHARS, size=(MAIN_WIDTH,MAIN_HEIGHT))
     
            self.index = 0
     
            self.list_ctrl = ULC.UltimateListCtrl(self, -1, agwStyle=ULC.ULC_REPORT|ULC.ULC_HAS_VARIABLE_ROW_HEIGHT)
            self.list_ctrl.InsertColumn(0, "Artist")
            self.list_ctrl.InsertColumn(1, "Title", wx.LIST_FORMAT_RIGHT)
            self.list_ctrl.InsertColumn(2, "Download")
     
            items = musicdata.items()
            index = 0
            for key, data in items:
                pos=self.list_ctrl.InsertStringItem(index, data[0])
                self.list_ctrl.SetStringItem(index, 1, data[1])
                #self.list_ctrl.SetStringItem(index, 2, data[2])
                button = wx.Button(self.list_ctrl, id=wx.ID_ANY, label="Download")
    	    self.list_ctrl.SetItemWindow(pos, col=2, wnd=button, expand=True)
                self.list_ctrl.SetItemData(index, key)
                index += 1
     
            # Now that the list exists we can init the other base class,
            # see wx/lib/mixins/listctrl.py
            self.itemDataMap = musicdata
            listmix.ColumnSorterMixin.__init__(self, 3)
            self.Bind(wx.EVT_LIST_COL_CLICK, self.OnColClick, self.list_ctrl)
     
            sizer = wx.BoxSizer(wx.VERTICAL)
            sizer.Add(self.list_ctrl, 1, wx.ALL|wx.EXPAND, 5)
            self.SetSizer(sizer)
     
    	
        def GetListCtrl(self):
            return self.list_ctrl
        
        #----------------------------------------------------------------------
        def OnColClick(self, event):
            pass
     
    ########################################################################
    class MyForm(wx.Frame):
     
        #----------------------------------------------------------------------
        def __init__(self):
            wx.Frame.__init__(self,None,wx.ID_ANY,'%s v%s' % (APPNAME,APPVERSION),size=(MAIN_WIDTH,MAIN_HEIGHT),style=wx.MINIMIZE_BOX | wx.SYSTEM_MENU | wx.CAPTION | wx.CLOSE_BOX | wx.CLIP_CHILDREN)
     
            # Add a panel so it looks the correct on all platforms
            panel = TestUltimateListCtrlPanel(self)
     
    #----------------------------------------------------------------------
    # Run the program
    if __name__ == "__main__":
        app = wx.App(False)
        frame = MyForm()
        frame.Show()
        app.MainLoop()
    Clicking on the column does not sort the 'Artist' or 'Title' fields. I want to be able to sort them when the user clicks on the column headers. Please help.

    Attached is the screen shot of how the frame looks like
