This seems like a bug. Html Helper classes are easy to extend, although after looking at the MVC source, looking for the bug, I gave up and just leveraged the premise that templates work for an individual item, so I wrote an HtmlHelper extension that wraps it for you. I took out the lambda expression for my own simplicity, but you can easily go back to that. This example is just for a list of strings.

    public static class DisplayTextListExtension
{
    public static MvcHtmlString DisplayForList(this HtmlHelper html, IEnumerable model, string templateName)
    {
        var tempResult = new StringBuilder();

        foreach (var item in model)
        {
            tempResult.Append(html.DisplayFor(m => item, templateName));
        }

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

Then the actual usage looks like:

                                @Html.DisplayForList(Model.Organizations, "infoBtn")
