Accessing Children property of drop down

Pretty new to Unity. Actually, a month in.
Doing networking for my game and working with the user interface.

I have a drop down button. That has a script attached to it. That will generate children on the fly depending on an event occurring (lets say a rollover). It generates the room names currently available simulating a lobby. The children class has an instance variable room name which is the name of the button generated which relates to the roomlist.

I am a bit stuck on how to grab that button name / room name on the click of one of those children buttons to join a room.
Any help or advice would be greatly appreciated.
Thanks

Figured it out. Derp.

private Button button { get { return childobj.GetComponent(); } } //getter

childEvents = button.onClick; //assign

childEvents.AddListener(delegate { JoinRoomSelected(); }); //method slected
