I wrote a login form in Blazor (with some MudBlazor elements) and now I’ve run the app but after filling in the form and pressing the Submit button nothing happens. What am I doing wrong?

<EditForm Style="width: 700px;" Model="@_loginModel" OnValidSubmit="OnValidLoginSubmit" FormName="LoginForm">
    <DataAnnotationsValidator />
    <MudGrid Style="width: 100%;">
        <MudItem Style="width: 100%;">
            <MudPaper Width="100%">
                <MudCardContent>
                    <MudTextField Label="Username or email" HelperText="Type either your username or email" @bind-Value="_loginModel.UsernameOrEmail" For="@(() => _loginModel.UsernameOrEmail)" ErrorText="@_loginUsernameErrorText" OnBlur="OnBlurCallback" />
                    <MudTextField Label="Password" HelperText="Type your password" Class="mt-3" @bind-Value="_loginModel.Password" For="@(() => _loginModel.Password)" InputType="InputType.Password" />
                </MudCardContent>

                @if (_backendLoginResponse is not null)
                {
                    <MudAlert Severity="Severity.Error">@_backendLoginResponse</MudAlert>
                }

                <MudCardActions>
                    <MudButton ButtonType="ButtonType.Submit" Variant="Variant.Filled" Color="Color.Primary" Class="ml-auto">Login</MudButton>
                </MudCardActions>
            </MudPaper>
        </MudItem>
    </MudGrid>
</EditForm>
