Cascade Drop Down - Child doesn't always fire

[David Elliott]

Here is an working example: http://jsfiddle.net/ayuoky3z/

You will see the 2 parents have a common child -> Number 2.

On Run

.  parent changed to 1

.  child changed to 1

Change to "Parent 2"

.  child changed to 2

.  OnChildChanged

.  parent changed to 2

.  OnParentChanged

Child is updated because there is no value 1

Change to "Parent 1"

.  parent changed to 1

.  OnParentChanged

Child is not updated because there is a value 2

What I want is when the parent changes then the child is notified whether or not it changed.  

I want to get the new value of the parent and child and then call out to an server and update the page.

Any help is appreciated

Would this work?

Storing the object as opposed to the value does seem to fix this problem.

Thanks
