How do i...how to fix my search using a select that is populated in razor

Razor

have a page that searches employees by campus. The campuses are populated in a select using razor. I then get all the filtered employees but the page refuses to redraw the DOM with the current number of employees

I have an onchange() of the select it calls an ajax that will call the ActionResult of the page. This somehow works fine since it returns the correct data.

What I have tried:

A select populated using razor

<select placeholder="Select campus" id="selCampus" class="form-control" required>
                                <option value="">Select campus</option>

                                @foreach (var campus in Model.Campuses)
                                {

                                    <option value="@campus.Id">@campus.CampusName</option>

                                    }
                                </select>

Onchange for the select pointing to the action controller

$("#selCampus").change(function () {
                //$(".employee").remove();
                $.ajax({
                    type: 'POST',
                    url: '/admin/staff/',
                    dataType: 'html',
                    data: ({
                        campusId: $(this).val()
                    }),
                    success: function () {
                    }
                });
            });

ActionResult, this loads on pageload and onchange of the select

public ActionResult Employees(long? campusId)
                {
                    var client = new RestClient(Request.Url.GetLeftPart(UriPartial.Authority).ToString());
                    var request = new RestRequest("api/employee/getClinicMembers/{campusId}", Method.POST);
                    request.AddParameter("campusId", campusId, ParameterType.QueryString);

                    var result = client.Execute<ClinicMembersOutput>(request);

                    ViewBag.title = "Home | Members";
                    return View(result.Data);
                }

Does not want to redraw this code with new data, Even tho Model.Employees has filtered data

@foreach (var member in Model.Employees)
                        {
                            <div class="col-lg-4 col-xlg-3 col-md-5 employee">
                                <div class="card">
                                    <div class="card-body">

                                    </div>
                                </div>


                            </div>

                        }
