OnChange() event of CheckBox of CRM 4.0

OnChange() event of the CheckBoxes done in the forms of CRM 4.0 is not fired the way it should be. Ironically you can see specific place to write the code and enable the event according to usual CRM concept.

Anyway, it is easy to write the same thing (actually onClick) in onLoad form and get the thing done. Write the even function in the onload as mentioned below.

MyDemoCheckbox = function()
{
    crmForm.all.new_mydemocheckbox.onclick = function() 
    {
       //Do what you need
    }
}

Hope this will work for you.
