Text Field in Split Button

I have table (Se) contains two column id(Primary key) and Name. Invoke metode getSe with set DBT equal to ${result.FirstOrDefault.Name}.
I use the metod for text field of split button .

But in such way I have only one field in the list of split buttton - first cell of column name.

What property in equal ${result.FirstOrDefault.Name}. I should replace in place of "FirstOrDefaut" to get a list of value from column Name in the split button when I using the ${DBT}?
