I am trying to implement auto complete textbox using MVC 4 Razor View. so i need to include include on attribute(`data-otf-autocomplete`) to the `HTML.EditorFor` control but it is showing error not allowing to add new attribute ?

Showing Error at :

```
 @Html.EditorFor(model => model.Subjects.Name, new { @data-otf-autocomplete="@Url.Action('Autocomplete_Subject')" });

```

**Note:** I can not edit/ change attribute name because that attribute is generated by 3rd party which was included in DLL component.
