Why doesn't the link follow?

Question

JavaScript

Guys, such a question, I made a modal window with a button, I hung an event on it so that it closes, but after closing it should follow the link, that is, search. When it is not in the modal, everything works, as soon as I open it in the modal, it does not go, why?

var fancy = $('.fancybox');
        fancy.fancybox();
        $(document).on('click', '.close_modal', function() {
            $.fancybox.close();
        });

Here is the button:

<button type = "submit" class = "btn close_modal"><TMPL_VAR lang_search></button>
