Add a button to cause page reload ?

I have successfully added a button but although it executes my code block I can't get it to reload the page. My code is :

<code>

editor.addCommand( 'footnoteCancel',
{

               exec : function( editor )
               {
                    // display the menu icon
                   jQuery("#block-block-2").show();
                   //refresh page to exit editor
                   //location.reload(true); doesn't work
                   document.location.reload(true);
               }
           });</code>

I'm a Javascript newbie so any suggestions would be helpful.

Thanks
