Your model should be something like this

public class MyViewModel
{
    public IEnumerable<string> Columns { get; set; }
    public IEnumerable<dynamic> Values { get; set; }
    public bool HasNext { get; set; }
    public bool HasPrevious { get; set; }
    public IEnumerable<CustomerModel> Customers { get; set; }
    public IEnumerable<SelectListItem> Jobs { get; set; }

    public CustomerModel Customer {get; set;}
}

In your view the code to add dropdown should be something like this

<%= Html.DropDownListFor(X=>X.Customer,Model.Customers) %>

Hope this helps.
