How to update checkbox of Row when filtering triggered?

pearlqueen

Hi,
I'm a beginner for dataTable. The first column of DataTable is checkbox which is used to identify the row is selected or not. I used columnFilter plugin to do custom filter. What I want to do is when user change the select of column in thead, the checkbox will be checked for all filter rows. So I used "fnRowCallback" function, but I found the function is triggered only once(during the dataTable initialism). Could you please help to identify the reason or provide some other methods? Thanks a lot.
