No, you are not understanding how the value attribute works. The value
attribute is reflected by the defaultValue property. The value
property is internal state, and will sometimes reflect the value
attribute (because it happens to specify the default value).

This also goes for the checked attribute. It's reflected by the
defaultChecked property. I suggest studying the forms chapter of
http://www.whatwg.org/html if you're interested in this.
