Why input do not bind value to variable in this code

I started learning inputs in Blazor. When I try run this code, it doesn't show any errors, but when I enter some text in the input control, then it won't show up in the <h1>...

<PageTitle>Home</PageTitle><h1>@Meno</h1><input class="form-control" @bind-value="@Meno" @bind-value:event="oninput" />@code {    private string Meno = "Jano";}
