[jQuery] Problem with a search form in a loaded php file??

hi,

have simple search form which works in list.php

Now i am 'loading' list.php in #content and now the search function
doesn't work.

what i have done
- change the type from submit to button
- in index.php i added

$("#content #search_button").click(function() {
                alert("click");
                var search_word = $("#searchTerm").val();
                var dataString = 'search_word='+ search_word;

                if(search_word=='')
                {
                alert("no searchterm");
                return false;
                }
                else
                {
                alert("search");
                }
        });

But the search_button isn't triggered??? How do i fix this??
