I'm trying to dynamically change (if it got clicked) a normal table header (which is a link) to another defined CSS class 'th.hilite'. This link simply sorts this column and the header should got highlighted every time a user sorts the list. 

The view where the class in question should be changed, looks like this:

```
%table#mytable
  %thead
    %tr
      %th= link_to 'Title', mytable_path(:sort => 'title'), :id => 'title_header'

```

My question is simply: **How and where could I dynamically set the class to %th.hilite if the header is clicked?**
