CheckBoxGroup Razor Change event

[idrissb]

If I have a checkboxgroup defined in my razor page as such

X.CheckboxGroup()
                                        .ID("chkPrograms")
                                        .ColumnsNumber(3)
                                        .FieldLabel("Programs")
                                        .AllowBlank(false)
                                        .Vertical(true)
                                        .PaddingSpec("2 10 6 2")
                                        .Listeners(l => l.Change.Handler = "function(this, newValue, oldValue, eOpts){ alert('1'); }")
                                        .Items(
                                            (from chk in Model.Programs
                                                 select new Checkbox
                                                 {
                                                     ID = chk.ProgramCode,
                                                     DataIndex = chk.ProgramCode,
                                                     InputValue = chk.ProgramCode,
                                                     BoxLabel = chk.ProgramCode
                                                 }
                                            ).ToList<Checkbox>()
                                       )

I would like to know which checkbox has been clicked so I can test some conditions.
this - returns the checkboxgroup
