Ajax.BeginForm model binding fails with SelectElement,Onchange

Question

I'm experiencing an odd issue . I got both a text input search field, and a dropdown list. I've set that with every change on the select menu it will submit said form with the values . It does bind the values but it bypasses the OnSuccess function and then basically things fall apart

Relevant Code:

  @Html.EnumDropDownListFor(x => x.AreaCodes, "בחר אזור", new
       {
           @class = "select_field w-select",
           onchange = "this.form.submit()"
       })



ReloadLocations = () => {

        $.ajax({
            url:`@Url.Action("LocationsList","Locations")`,
            method: 'POST',
            dataType: 'html',
            contentType: 'charset=utf-8',
            success: function (data) {
                $("#LocationList").empty();
                $("#LocationList").append(data);



            },

In this version it submits the form, However it goes straight to the function without actually going into the "success" part of the ajax call, Just returns a view. which results in me getting a partial view back. How can I fix this?

Edit: Full Controller Methode:

    {
 public ActionResult LocationsList(SearchLocationVM searchVm)
        var locationsVM = new List<LocationVM>();
        var locations = new List<Locations>();
              var searchTerm = searchVm.SearchTerm;
                var searchArea = (int)searchVm.AreaCodes;
        using (var unitOfWork = new UnitOfWork(new FriendsEntities()))
        {
            if (searchVm.AreaCodes == 0 && string.IsNullOrWhiteSpace(searchVm.SearchTerm))
            {
                locations = unitOfWork.Locations.Find(x => x.Visibility).OrderBy(x => x.Order).ToList();
                locationsVM = locations.Select(x => new LocationVM()
                {


                    ActivityHours = x.location_open_time ?? string.Empty,
