In the bind() method, checking if the event returned false

In the bind() method, checking if the event returned false

Hi,
In the following bind() method, how do I check if the event has returned false:
  1. .find( 'button.save' )
  2.     .bind( 'click', function( event ) {
  3.         if (?? != false) {
  4.             self.save( self.element, event );
  5.              self.change( self.element, event );
  6.         }
  7.         return false;
  8.         })
  9.     .end()

Here's the event code:
  1. $('.doc_editable').inlineEdit({
  2.     save: function( event, hash ) {
  3.         var loadUrl = "phpparts/document.php";
  4.         var messageDiv = "#doc_message";
  5.         if (!updateValue(loadUrl, hash.value, this.id, messageDiv)) {
  6.             return false;
  7.         }
  8.    }
  9. });

Appreciated..
