How can i filter select box with appended values?

Hi guys,

I created a view with two filter box and two selectbox.
When user type a value in the filter box it will filter the related selectbox.
And when user clicks on an element in the select box it will transfer the item to the other selectbox, vice verse.
Problem is the 2nd filter is not working..

Please take a look at my code here.


PS: please expand the view screen alittle. My UI is quite wide.

Thanks in advance!
