Does this code fragment can be in another?

Hello friends. I need this code:

  1.   $('ul.modelos > li').one("click", function() {
  2.     $(this).not(':first-child').append('<span class="visto_mod"></span>')
  3.   });
May be included in another:

  1.      $('ul.modelos > li').click(function () {     
  2.         ... ;
  3.       here  (only one click) ;
  4.         ... ;
  5.      return false; 
  6.      });
    
 Can it be?
