Reload select filter options

adolfotcar

Hello, I'm afraid I'm doing something very stupid. I'm trying to put a select filter for each column I have in my table, but I also need that the values of these selects are reloaded every time a filter is changed, and always containing only the available options.
I found the answer here: http://datatables.net/forums/discussion/8888/select-column-filtering
But I don't know where to put the code given by @gaadek...I know is something stupid, but after hours I still can't put it to work.
Thanks.
