Blazor submit button

I am starting with Blazor and I want add data to DB. But after filling InputTexts submit button not working (Not going to InsertUser).

Here is my code:

@page "/Users"@using DataAccessLibrary@using DataAccessLibrary.Models@using Models@inject IUserData _db@rendermode InteractiveServer<h3>Users</h3><h5>Insert new user</h5><EditForm FormName="Insert" Model=@newUser OnInvalidSubmit="@InsertUser"><DataAnnotationsValidator /><ValidationSummary /><div class="form-group"><InputText id="UserName" @bind-Value="newUser.UserName" class="form-control" /> <br /><InputText id="FullName" @bind-Value="newUser.FullName" class="form-control" /><br /><InputText id="Password" @bind-Value="newUser.Password" class="form-control" /></div><br /><input type="submit" class="btn btn-primary" value="Save" /></EditForm>@code{    private List<UserModel> user;    public DisplayUserModel newUser = new DisplayUserModel();    protected override async Task OnInitializedAsync()    {        user = await _db.GetUsers();    }    private async Task InsertUser()    {        UserModel us = new UserModel            {                UserName = newUser.UserName,                Password = newUser.Password,                FullName = newUser.FullName            };        await _db.InsertUsers(us);        user.Add(us);        newUser = new DisplayUserModel();    }}

Can you please help me....
