Can I update a hidden column

Hi,

Great work on datatables - thanks.

I have a datatable which has some input fields in it. To allow filtering and searching I put the value from inside the input into a hidden column and use this for filtering and searching (so search/filter doesn't include the INPUT HTML tags). Is there a way that onchange() of the input I can change the value in the hidden column to the new value in the input so that the filtering and searching still works?

Thanks,
Ed
