Individual column searching (select inputs)-not working weblink data in tables

n1x0n

I use datatable , and it generates the json , 4 column (product , category , manufacturer, price )
Data Type column in the "category name" is a type of web link as <a href="/category_weblink.html">simple Category</a>
Default version of the table looking for and executes all commands excellent, but it took me to make select sorting by category and here there was a problem . Data from the plain text(product,price,manufacter) format sorts the selectivity is good, but the column data type - web links does not filter!!! , Answer no data to display 0
