I have a custom module with a view that lists some data from a web service and has some filters in it (date, numeric, combos, etc). I need to modify some filters when others change their value. For example, When the user changes the date, I have to change the selected value of a combo box. I was trying to pass the filter values to a javascript file, but I couldn't find a way yet. I tried using the "page_attachments" hook and a controller but none of them work.

Can somebody point me in the right direction on how I can do this? Thanks in advance.
