Updating customer info on order page viewcart template

Hello,

I updated viewcart.tpl and make inputs editable before ordering (if client has an empty info they can enter it before ordering.)

I mean,

from:

<td class="fieldarea">{if $loggedin}{$clientsdetails.firstname}{else}<input type="text" class="form-control" name="firstname" tabindex="1" value="{$clientsdetails.firstname}" />{/if}</td>

to:

<td class="fieldarea">{if $loggedin}<input type="text" class="form-control" name="firstname" tabindex="1" value="{$clientsdetails.firstname}" />{else}<input type="text" class="form-control" name="firstname" tabindex="1" value="{$clientsdetails.firstname}" />{/if}</td>

So, clients can update their info when they are giving an order.

But system is not getting those values and save them to clients profile.

What do i need to do to make it work? For V5 latest.

Thanks.

So nobody knows
