Datatables: Filter plugin won't work if table was set to 'serverSide'

Hello, I'm trying to figure out why the Filter plugin won't work if a table has serverSide: true. When I set it to false, like in the examples, it works perfectly, but I need it to be server-side because I will be listing a lot of rows. Everything else, such as pagination and sorting, works in both cases.

Thanks in advance.
