I keep getting a Return value of underfined...

How would I make this function return the actual html value but by keeping a post occur :

  2.  function clicky() {
  3.             var thisHTML1;
  4.             $(document).on('click', '#htTab a', function() {
  5.                 var thisHTML = $(this).html();
  6.                 thisHTML1 = thisHTML;
  7.                 return false;
  8.             });
  9.             alert("TESTING");
  10.             return thisHTML1;
  11.         }
