Again, you will never see the value of any field if you use "View Sourcecode", you will only see what the browser downloaded when requesting the page. Any changes you make to the page are stored but they do not have an effect on the source code itself.
But if you temporarily change the type of those fields to "text", you can see that they change on the page, but the sourcecode will always stay intact. That is ok since the browser does not use the sourcecode to keep track of the values of fields etc when a page is dynamically changed with scripts.
If you want to store a change on the page during a refresh, you either need to write a cookie and read it when the page loads, or send the data to the server so it can rewrite the sourcecode and make it have the changes before sending it back to the browser.
