Hi I have this code:

    @inherits Umbraco.Web.Mvc.UmbracoViewPage<ContentModels.TwoColumnPage>
@using ContentModels = Umbraco.Web.PublishedContentModels;

@{
    ViewBag.Title = "...";
    Layout = "...";
}
<div class="container">
    <div class="row">
        <div class="col-sm-12 col-lg-6">
            One of 2 columns
        </div>
        <div class="col-sm-12 col-lg-6">
            @Html.Partial("~/Views/Partials/Right.cshtml",
        new myNamespace.Models.myContentList()
        {
            Target=Model.Content.target,

            Text=Model.Content.SomeText,
            somelist=Model.Content.Somelist
        }
        )
        </div>

    </div>
</div>

The problem is with the class. First TwoColumnPage is not recognized. This is actualy my Document Type. Then Model.Content doesn't contain target, someList and sometext.

Please advice how to fix this
