MVC Processing Index of collection elements in a partial view model

I have a ViewModel with a collection inside, for example:

public class CreateCampaignViewModel : ControlPanelViewModel
{
    [RequiredField]
    public string Name { get; set; }

    public List<AdvertisementViewModel> Advertisements { get; set; }
    ...
}

in the view, if I use it like:

@for (int i = 0; i < Model.Advertisements.Count; i++)
{
  <fieldset style="z-index: 0;">
  <legend>מודעה</legend>
  <table style="width: 100%;">
    <tr>
      <td>
        <label for="@Html.NameFor(m => m.Advertisements[i].Title)">כותרת הפרסומת</label></td>
      <td>@Html.TextBoxFor(m => m.Advertisements[i].Title)</td>
    </tr>
  </table>
  </fieldset>
}

everything is fine and i see the list when i submit the form ...

but I want to insert an ad editor in a partial view, so my view will look like this:

@for (int i = 0; i < Model.Advertisements.Count; i++)
{
   Html.RenderPartial("AdvertisementEditor", Model.Advertisements[i]);
}

and my Partial:

@model Pushed.Models.AdvertisementViewModel

<fieldset style="z-index: 0;">
    <legend>מודעה</legend>
    <table style="width: 100%;">
        <tr>
            <td>
                <label for="@Html.NameFor(m => m.Title)">כותרת הפרסומת</label></td>
                <td>@Html.TextBoxFor(m => m.Title)</td>
        </tr>
    </table>
</fieldset>

My problem is that now when I submit the form, I don’t get the value in the text box for each ad.

This is logical because now the tags <input>do not have the name 'advert [1] .Title', but only the 'Title', which is not in my containing model.

How can I create a partial one that reflects one element of the collection that it works with so that it displays the form correctly?

      new ViewDataDictionary {
           TemplateInfo = new TemplateInfo {
               HtmlFieldPrefix = "Advertisements[4]" // 4 being an example
           }
