Blazor EditForm Validation not working when using Child Component

I have a Blazor component called EditOffice. It looks as follows:

<EditForm Model="@Office" OnValidSubmit="@HandleValidSubmit"><DataAnnotationsValidator /><ValidationSummary /><InputTextRow Label="Name" @bind-Value="@Office.Name" Placeholder="Enter name" /><InputTextRow Label="ABN" @bind-Value="@Office.ABN" Placeholder="Enter ABN" />...<button type="submit" class="btn btn-primary edit-btn">Save office</button></EditForm>

I created child components called InputTextRow in an attempt to Tidy my code. They look as follows:

<div class="form-group row"><label for="@Id" class="col-sm-3">@Label: </label><InputText id="@Id" @oninput="OnValueChanged" @bind-Value="@Value" class="form-control col-sm-8" placeholder="@Placeholder"></InputText><ValidationMessage class="offset-sm-3 col-sm-8" For="@(() => Value)" /></div>@code {    public string Id => Label.ToLower().Replace("", "");    [Parameter]    public string Label { get; set; }    [Parameter]    public string Value { get; set; }    [Parameter]    public string Placeholder { get; set; }    [Parameter] public EventCallback<string> ValueChanged { get; set; }    Task OnValueChanged(ChangeEventArgs e)    {        Value = e.Value.ToString();        return ValueChanged.InvokeAsync(Value);    }}

The ValidationMessage doesn't work when in my child component. Any idea why?
