Customizing Html.LabelFor

Question

I'd like to add some classes to my labels, so I added Label.cshtml Under Shared/EditorTemplates folder. It seems Razor is ignoring it. I've tried DisplayTemplatesfolder too, but it didn't work neither.

Can I have editor template for labels? If no, what's the best way to customize them?

Label.cshtml:

@model object

@Html.LabelFor(m => m, new { @class = "col-xs-4 control-label" })

UPDATE:

This is my code that I took from this post and with some changes from this useful link. It still doesn't work, I don't know what's going on. Can anyone help?

public static class Extensions
{
    public static MvcHtmlString LabelFor<TModel, TValue>(this HtmlHelper<TModel> html, Expression<Func<TModel, TValue>> expression, object htmlAttributes)
    {
        return LabelFor(html, expression, new RouteValueDictionary(htmlAttributes));
    }
    public static MvcHtmlString LabelFor<TModel, TValue>(this HtmlHelper<TModel> html, Expression<Func<TModel, TValue>> expression)
    {
        return LabelFor(html, expression, null);
    }
    public static MvcHtmlString LabelFor<TModel, TValue>(this HtmlHelper<TModel> html, Expression<Func<TModel, TValue>> expression, IDictionary<string, object> htmlAttributes){

        ModelMetadata metaData = ModelMetadata.FromLambdaExpression(expression, html.ViewData);
        string FieldName = ExpressionHelper.GetExpressionText(expression);
        string LabelText = metaData.DisplayName ?? metaData.PropertyName ?? FieldName.Split('.').Last();
        if (string.IsNullOrEmpty(LabelText))
            return MvcHtmlString.Empty;
        TagBuilder tag = new TagBuilder("label");
        tag.MergeAttributes(htmlAttributes);
        tag.SetInnerText(LabelText);
        tag.Attributes.Add("for", html.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldId(FieldName));
        tag.Attributes.Add("class", "control-label col-xs-2");
        return MvcHtmlString.Create(tag.ToString());
    }
}

EditorTemplate's are based on the type of a property (not on the html element they generate). You would need to create your own html helper

public static MvcHtmlString BootstrapLabelFor<TModel, TValue>(this HtmlHelper<TModel> helper, Expression<Func<TModel, TValue>> expression)
{
  var attributes = new { @class = "col-xs-4 control-label" };
  return helper.LabelFor(expression, attributes);
}

and use it in the view as

@Html.BootstrapLabelFor(m => m.yourProperty)

However this seems an inflexible way to use a helper just to save adding the html attributes in the standard LabelFor() helper. Perhaps it might be more useful to combine the associated textbox and validation message in the one helper as per this answer (Note this answer also shows how to add the namespace to the web.config file
