The value attribute should update the hidden element value if no data-value is provided

[amsul]

Upon initialization, a value using the format doesn’t update the hidden element. This was purposely done to allow developers to set a default value on load while specifying hidden values using the data-value.

For example:

<input type="text" value="Unedited value: January 24, 2013" data-value="2013-24-01" />
<input type="hidden" value="2013-24-01" />

...after selecting something would change to:

<input type="text" value="January 25, 2013" data-value="2013-24-01" />
<input type="hidden" value="2013-25-01" />

However, without a data-value attribute, it should still work seamlessly.

Expected:

<input type="text" value="January 24, 2013" />
<input type="hidden" value="2013-24-01" />

Actual:

<input type="text" value="January 24, 2013" />
<input type="hidden" value="" />

thank you.

As mentioned here data-value is for storing custom data not the standard way of storing and accessing the form input value.
