[asp.net-mvc] ActionLink htmlAttributes

WORKS

<a href="@Url.Action("edit", "markets", new { id = 1 })" 
            data-rel="dialog" data-transition="pop" data-icon="gear" class="ui-btn-right">Edit</a>

DOES NOT WORK - WHY?

@Html.ActionLink("Edit", "edit", "markets", new { id = 1 }, new {@class="ui-btn-right", data-icon="gear"})

It seems you can't pass something like data-icon="gear" into htmlAttributes?

Suggestions?

Replace the desired hyphen with an underscore; it will automatically be rendered as a hyphen:

@Html.ActionLink("Edit", "edit", "markets",
    new { id = 1 },
    new {@class="ui-btn-right", data_icon="gear"})

becomes:

<form action="markets/Edit/1" class="ui-btn-right" data-icon="gear" .../>

@Html.ActionLink("display name", "action", "Contorller"
    new { id = 1 },Html Attribute=new {Attribute1="value"})
