Partial view inside main view + save to DB

I am making a site for entering metadata. On the first tab (CSS tabs) I have few dropdowns and after you make the choices, the second tab is unlocked.

Right now the second tab is empty, and the contend that is supposed to go there, I have put it in another view. It looks like this.

Now, what I want to achieve is - when I open the second tab the view in the second picture should be shown, loaded as @Html.Partial. So, after I make the choices in the first tab, select one of the items in the list in the second tab, and written some text in the editor, all of that should be saved to the DB.

Here is the controller action for the list in the second tab:

    public ActionResult asdf()
    {
        List<SIMS_Test> all = new List<SIMS_Test>();
        using (UsersContext dc = new UsersContext())
        {
            var LanguageID = Thread.CurrentThread.CurrentUICulture.Name;

            if (LanguageID == "en-US")
            {
                all = dc.SIMS_Test.Where(s => s.LanguageID == "en-US").OrderBy(a => a.ID).ToList();
            }
            else
            {
                all = dc.SIMS_Test.Where(s => s.LanguageID == "mk-MK").OrderBy(a => a.ID).ToList();
            }
        }
        return View(all);
    }

The problem is the partial view cannot be loaded inside the main view because they use different models in the views:

@model MvcApplication20.Models.MetapodatociModel

and

@model List<MvcApplication20.Models.SIMS_Test>

Can this be done this way, but also, can it take the values of the partial view, give them to the controller action of the main view so that all this can be saved in the DB?

Edit: Here are the models:

public class MetapodatociModel
{
    [Required(AllowEmptyStrings = false, ErrorMessageResourceType = typeof(Resources.Home), ErrorMessageResourceName = "StringDD1Empty")]
    public string Domen { get; set; }
    [Required(AllowEmptyStrings = false, ErrorMessageResourceType = typeof(Resources.Home), ErrorMessageResourceName = "StringDD2Empty")]
    public string Istrazuvanje { get; set; }
    [Required(AllowEmptyStrings = false, ErrorMessageResourceType = typeof(Resources.Home), ErrorMessageResourceName = "StringDD3Empty")]
    public string Frekvencija { get; set; }
    [Required(AllowEmptyStrings = false, ErrorMessageResourceType = typeof(Resources.Home), ErrorMessageResourceName = "StringDD4Empty")]
    public string Period { get; set; }
    [Required(AllowEmptyStrings = false, ErrorMessageResourceType = typeof(Resources.Home), ErrorMessageResourceName = "StringDD5Empty")]
    public string Godina { get; set; }
    [AllowHtml]
    [UIHint("tinymce_full")]
    public string TestPole { get; set; }
}

[Table("SIMS_Test", Schema = "sims")]
public class SIMS_Test
{
    [Key, Column(Order = 0)]
    public int ID { get; set; }
    public string SIMSCode { get; set; }
    public string Inheritance { get; set; }
    [Key, Column(Order = 1)]
    public string LanguageID { get; set; }
    public int LevelId { get; set; }
    public int QualityId { get; set; }
    public string ConceptName { get; set; }
    public string ConceptCode { get; set; }
    public string Descriptions { get; set; }
    public string Representation { get; set; }
    public string ESSGuidelines { get; set; }
    public int? OrderId { get; set; }
}
