Multimple autocomplete boxes, one filtering ajax datasource. How to pass the id of the box?

[Rey]

I have multiple autocomplete boxes and they all filter through the same AJAX datasource.  I want to somehow pass the ID of the specific box to the AdditionalData javascript function so that I don't have to write like five different JavaScript functions with pretty much the same logic.  I didn't see anything in the documentation and passing "e" in the AdditionalData function just passes the filter.

Razor:

<strong>To:</strong>  Html.Kendo().AutoComplete().Name("ToAddress")
                    .DataTextField("Email")
                    .Separator(";").MinLength(4).Filter(FilterType.Contains)
                    .DataSource(source =>
                    {
                        source.Read(r =>
                        {
                            r.Action("SearchAD", "Home").Data("AdditionalData");
                        })
                        .ServerFiltering(true);
                    }))

<strong>CC:</strong>  Html.Kendo().AutoComplete().Name("ccAddress")
                    .DataTextField("Email")
                    .Separator(";").MinLength(4).Filter(FilterType.Contains)
                    .DataSource(source =>
                    {
                        source.Read(r =>
                        {
                            r.Action("SearchAD", "Home").Data("AdditionalData");
                        })
                        .ServerFiltering(true);
                    }))

            
<strong>BCC:</strong>  Html.Kendo().AutoComplete().Name("bccAddress")
                    .DataTextField("Email")
                    .Separator(";").MinLength(4).Filter(FilterType.Contains)
                    .DataSource(source =>
                    {
                        source.Read(r =>
                        {
                            r.Action("SearchAD", "Home").Data("AdditionalData");
                        })
                        .ServerFiltering(true);
                    }))

JavaScript

    function AdditionalData() {
        var text = $("[the autocomplete id]").val();  //get the ID or any other identifier
        var i = text.indexOf(";");
        var value = text.substring(i + 1);
        return {
            text: value
        }
    }
