I understand that fields such as Html.TextBox() accept two values, the first one being the name and the second one being the value. And so does Html.TextArea(). But in a case where the form is submitted as AJAX and the div where the form is placed is replaced with a view from the server, the form fields insist on taking the previous values. An image is worth a thousand words:

I’ve checked everything on the controller and the model and the image is from debugging the view itself. The model is empty but the fields generated from it take the value of the previous submission.
