Sense Developer: Masterobject name in Dropdown view

[BU]

Hi All, i'm a new Extension Developer and i'm trying to do a sortable by user dropdown!! 

I've created the dropdown following the QlikDev guidelines 

but when i've a problem with masterobject's name props.name (that's a dropdown of filterpane objects). the field props.name contains an id but i want to show the name of the field!

Has anyone an idea to get masterobject's name?

Ty so much!
