search conflict with Alphabet input search

WYC

I tried to implement a page with 2 DataTables search functions (search different fields). One is Alphabet Input Search I got from https://www.datatables.net/blog/2014-09-02#; the other is a regular DataTable. If I click on the search letters on the top of Alphabet Input Search the 2nd DataTable search can only limit to the letter was clicked on the Alphabet Input Search. Example is at http://live.datatables.net/ledoheje/1/edit. I used the same dataset for example purpose. Any input would be appreciated.
