下拉列表是從同一個模板生成不同

所以我有了它使用下面的模板下拉列表是從同一個模板生成不同

@using DigitalDjPool.Website.Domain.Profiles 
@model DigitalDJPool.Website.UI.Models.ProfileWizard.UserDJTypeModel 

<div class="row no-margin"> 
    <div class="input-field col m4 s12"><h5>What type of DJ are you?</h5> 
    </div> 
    @Html.HiddenFor(m => m.UserMemberTypeId) 
    <div class="input-field col m4 s12"> 
     @Html.DropDownListFor(m => m.SelectedMemberType, ((IEnumerable<MemberType>)Model.MemberTypesList) 
      .Select(t => new SelectListItem { Value = t.Id.ToString(), Text = t.Name, Selected = t.Id.ToString().CompareTo(Model.SelectedMemberType) == 0 }), new { @class = "editprofile-info-ddl" }) 
    </div> 
    <div class="input-field col m4 s12"> 
     @Html.TextBoxFor(m => m.MemberTypeInfo) 
     @Html.ValidationMessageFor(m=> m.MemberTypeInfo) 
    </div> 
</div> 
<div class="row no-margin"> 
    <div class="input-field col m4 s12"><h5> What is your typical audience size? </h5></div> 
<div class="input-field col m4 s12"> 
    @Html.DropDownListFor(m => m.AudienceSize, new List<string> {"1-50", "50-499", "500+"}.Select(t => new SelectListItem {Value = t, Text = t, Selected = t == Model.AudienceSize})) 
</div> 
    </div>

，當我最初創建的頁面的下拉列表出來的權利一些奇怪的原因DJTypeModel列表的類ProfileViewModel 但是當我使用ajax調用將另一個UserDjTypeModel添加到頁面時，我收到的html腳本將螺絲鎖定在下拉列表中。我收到的代碼與chrome視圖源代碼頁中的代碼相同，但是當我檢查元素時，頁面加載期間創建的代碼會有另一個標籤。我已經檢查過，沒有運行JSScript。該folloing的代碼所示在源頁面，並在HTML通過AJAX返回

<div class="row no-margin UserDjTypeModelObj"> 
 
    <div class="input-field col m4 s12"><h5>What type of DJ are you?</h5> 
 
    </div> 
 
    <input id="UserDJTypeModel_0__UserMemberTypeId" name="UserDJTypeModel[0].UserMemberTypeId" type="hidden" value="2ad4c348-0120-4eeb-b031-a5b0008d0d43" /> 
 
    <div class="input-field col m4 s12"> 
 
     <select class="editprofile-info-ddl" id="UserDJTypeModel_0__SelectedMemberType" name="UserDJTypeModel[0].SelectedMemberType"><option value="f4579c21-8509-49df-9329-00fc33bd3344">College Radio</option> 
 
<option selected="selected" value="8f670bf6-1a95-4c30-abac-2acac6fd3e05">FM Radio</option> 
 
<option value="b9b14aca-81d2-49a1-9393-3c2e6552ff71">Mobile DJ</option>

</select> 
 
    </div> 
 
    <div class="input-field col m4 s12"> 
 
     <input id="UserDJTypeModel_0__MemberTypeInfo" name="UserDJTypeModel[0].MemberTypeInfo" type="text" value="98.7" /> 
 
     <span class="field-validation-valid" data-valmsg-for="UserDJTypeModel[0].MemberTypeInfo" data-valmsg-replace="true"></span> 
 
    </div> 
 
</div> 
 
<div class="row no-margin"> 
 
    <div class="input-field col m4 s12"><h5> What is your typical audience size? </h5></div> 
 
<div class="input-field col m4 s12"> 
 
    <select id="UserDJTypeModel_0__AudienceSize" name="UserDJTypeModel[0].AudienceSize"><option value="1-50">1-50</option> 
 
<option value="50-499">50-499</option> 
 
<option selected="selected" value="500+">500+</option> 
 
</select> 
 
</div>

這是返回的對象怎麼弄出來，你可以看到兩個下拉列表失敗雖然html代碼有顯示
