You should use MvcHtmlString class to implement razor extenuation method. like this.

I'have implemented it for Spanfor properties. you can implement by using this approach

below code will help you as an idea.

public static MvcHtmlString SpanFor<TModel, TProperty>(this HtmlHelper<TModel> html, Expression<Func<TModel, TProperty>> expression, object htmlAttributes)
        {
            var valueGetter = expression.Compile();
            var value = valueGetter(html.ViewData.Model);

            var span = new TagBuilder("span");
            span.MergeAttributes(new RouteValueDictionary(htmlAttributes));
            if (value != null)
            {
                span.SetInnerText(value.ToString());
            }

            return MvcHtmlString.Create(span.ToString());
        }

I hope this will help you.
