You need to invoke the parent page reload from the child at the time of closing. Few discussed
here.[

Try:
window.close();
if (window.opener && !window.opener.closed) {
window.opener.location.reload();
}
Alternatively,
If you are using ModalDialog then you will have control on when the window was closed in Parent page itself. You can use that as an event to reload the parent page. Have a look at the example
here.[
