How to insert validator in Template Editor for Integer?

Question

ASP.NET

Why for integer if I do in view:

@Html.EditorFor(Function(model) model.BalanceCalls)
@Html.ValidationMessageFor(Function(model) model.BalanceCalls, "")

The validator fires. And if I put the code in the editor template for integer:

@ModelType Integer
@Html.TextBox("", Model)
@Html.ValidationMessageFor(Function(model) model, "")

The validator is not working. The same construction with strings works fine.
I do the check Required
