You are using the overload of EditorFor() that passes the object as additionalViewData. You can read that within the template from the ViewDataDictionary

@model int?
@{ var attributes = ViewData["htmlAttributes"]; } // returns { @readonly = "readonly" }

which you could then merge with your existing attributes and use in the TextBoxFor() method.

@{
    var htmlAttributes = HtmlHelper.AnonymousObjectToHtmlAttributes(attributes);
    htmlAttributes.Add("oninput", "this.value=this.value.replace(/[^0-9]/g,'')";
}
@Html.TextBoxFor(model => model, htmlAttributes)

Note that TextBoxFor() generates type="text" so there is no need to add it again. In addition, you do not need the leading @ unless its a reserved keyword (for example @class = "...")
