Kendo MVC - DropDown in grid not binding to model on update

Question

I pretty much have this entire grid working, but I'm unable to figure out two things.

1. How come my drop down list, when I change the value isn't making it to my model in my update
2. How do I keep the selected value from the model as the default value when I chose to edit my record.

I started with these two solutions to try to get here: Telerik example Telerik Example 2

Any help is appreciated, I can understand that this new DropdownList isn't being bound with the model, but i'm not entirely sure how to connect them. In my database the ProspectStatus is an int but I am returning it as a string, the dropdownlist is all possible values. The grid is bound correctly, the dropdownlist is bound correctly, but I don't know how to get the new selected dropdownlistvalue to the ActionResult EditingInline_Update

Here is my index.cshtml

@{
    ViewBag.Title = "TC";
}
@using Kendo.Mvc.UI
<style>
    #grid {
        /* chop the grid's height by 45px */
        height: calc(100% - 45px);
    }

        #grid .k-grid-content {
            /* chop the grid content's height by 25px */
            height: calc(100%% - 25px) !important;
        }
</style>
<div id="grid" style="height:100%">

Here is my ApartmentProspectViewModel

using System.Web;
using Cleaner.Model;

namespace CleanerWebsite.Models

        public int ApartmentId { get; set; }
        public string PropertyTitle { get; set; }
        public string PropertyAddress { get; set; }

        public string PhoneNumber { get; set; }
        public string SourcePhoto { get; set; }

        [UIHint("ProspectStatusEditor")]
        public string ProspectStatus { get; set; }
        public DateTime? ProspectStatusDate { get; set; }
    }
}

here is my ProspectStatusEditor.cshtml

@using Kendo.Mvc.UI
@model CleanerWebsite.Models.ApartmentProspectViewModel
    
@(
Html.Kendo().DropDownList()
    .Name("Type")
    .DataTextField("IdValue")
    .DataValueField("Id")
    .OptionLabel("Select Status...")
    .DataSource(source =>
    {
        source.Read(read =>
        {
            read.Action("ProspectStatusList", "Home");
        })
        .ServerFiltering(false); ;
    })
)

just found it @model CleanerWebsite.Models.ApartmentProspectViewModel should be @model CleanerWebsite.Models.ProspectStatusModel
