razor: post value is old value (unaltered)

Question

I have a simple form:

            <form method="post" enctype="multipart/form-data" asp-page-handler="Button_Submit">
              
                <input value="@Model.yolonese.test" name="hi" />
                <input style="width: 30% !important; opacity: 0.2; " value="Weiter" class="baseButton" type="submit">

            </form>

a page model:

        public class Skills : PageModel
        {
    
        public Yolonese yolonese { get; set; }
        public Skills()
        {
        }

        public void OnGet()
        {
            yolonese = new Yolonese();
        }
        public void OnPost(Yolonese model)
        {
        }
    
    }

and a model:

public class Yolonese
{
    public string test { get; set; } = "test";
}

When my page is rendered, the input value displays "test". When I alter the value and check for what is posted, "test" is returned. Irregardless of what I wrote into the input.

Why is that?

Answer 1

The issue is, you cannot bind to an input the way I did, best to use this:

 @Html.TextBoxFor(m => m.test)

then the values simply written on the model without the need of an extra controller
