<div class="span3">
    @for (var i = 0; i < Model.GroupNames.Count; i++)
    {
        <ul>                 
            <li>
                @{
                    var item = Model.GroupTypeNames[i];
                    var selected = i == 0 ? " class=\"selected\"" : "";
                }

                <a onclick="getGroupType(@item.Id);" data-option-value="*"@Html.Raw(selected)>@item.TypeName</a>
            </li>
        </ul>
    }
</div>

function getGroupType(id) {
    debugger;
    $.getJSON( "Groups/Get" + id, function (data) {
        $(".span9").html($("#GroupTemplate").removeData());
        $.each(data, function (index, value) {
            if (value.Id != undefined) {
                $("#GroupTemplate").tmpl(value).appendTo(".span9");
            }
        });

        $('#circle').css("opacity", "0.5");
    });
}
