Raise an error from child component on text edit and catch it in the parent - Blazor

We have a parent component and a child component :I want to raise an event from the child (on text entering), catch it in the parent and do some actions.

In child component (razor) :

<InputText class="input-field"                   Value="@ProductModel.ModelNumber"                   @oninput="HandleInputChanged" />

In Code-behind:

[Parameter] public EventCallback<string> OnModelChanged { get; set; }private async Task HandleInputChanged(ChangeEventArgs e){    var newValue = e.Value?.ToString();    ProductModel.ModelNumber = newValue;    await OnModelChanged.InvokeAsync(newValue); }

In Parent Component (Razor):

<ChildFields ProductModel="ProductModel" OnModelChanged="HandleModelChanged" />

Code-Behind :

    [Parameter]    public ProductUpdateDto ProductModel { get; set; } = new()    {        ProductDiscriminator = nameof(Product)    };    private void HandleModelChanged(string newValue)    {        Console.WriteLine($"Model changed to: {newValue}");        RefreshAutoPath();    }    protected override async Task OnParametersSetAsync()    {        if (ProductModel != null)        {             ProductModel.ModelNumberChanged += RefreshAutoPath;        }                   await base.OnParametersSetAsync();    }

In DTO also I made a change to get notified:

    [StringLength(100)]    public string? ModelNumber    {        get => _modelNumber;        set        {            if (_modelNumber != value)            {                _modelNumber = value;                ModelNumberChanged?.Invoke();            }        }    }    public event Action? ModelNumberChanged;

I tried 3,4 different variations and in each got some errors.

As an example current error is:

Error: System.InvalidOperationException: Microsoft.AspNetCore.Components.Forms.InputText requires a value for the 'ValueExpression' parameter. Normally this is provided automatically when using 'bind-Value'.
