onChange event not firing Blazor InputSelect

I have the following Code for an InputSelect

<InputSelect class="form-control form-control form-control-sm"                             placeholder="Role"                             disabled="@IsReadOnly"                             @bind-Value="Model.Role"                              @onchange="@RoleChanged"><option value="Member">Member</option><option value="Admin">Admin</option><option value="Pioner">Pioneer</option><option value="Retailer">Retailer</option></InputSelect>

And for the Code:

bool ShowCreated;bool ShowUpdated;bool IsReadOnly;string SelectedRole;public EditForm AccountForm;public Multi.Dtos.RegistrationDto Model = new Dtos.RegistrationDto() { Role = "Member" };public void RoleChanged(ChangeEventArgs e){    SelectedRole = e.Value.ToString();    Console.WriteLine(e.Value);}

The RoleChange function is not invoked when i try to select a new item. Can someone point out what wrong with this. The value of the proper has changed but the Event was not called.
