Hello! Sorry for late reply. Could you clarify what exactly doesn't work? To retreive all selected checkboxes use the following code:
codeAppery("checkBoxGroupName").find("input:checked").each(function(){
alert($(this).val());
});/code
to check what radio button is selected use this code:
codeAppery("radioGroupName").find(":checked").val();/code
Also there is Value Change event inside the builder which works for radioGroup and checkBoxGroup components.
