I solved it.

I was using a:jsFunction tag as it follows:

  <script type="text/javascript">
        function getUserId(){
                var user = MyCompany.get_User();
            return user;
        }
    </script>

<a:jsFunction action="#{user.performLogin()}" name="doSiteLogin"  >
   <a:actionparam name="uid" value="getUserId()"/>
</a:jsFunction>

If you use the property noEscape="true" on the a:actionparam ... it call your javascript code.
