[luci] How to get a section name

[edwin]

Hi,

I have a typedsection as below:

s = m:section(TypedSection, "channels",
translate("Channels"),translate("Channels to be monitored or controlled"))
s.addremove = true

I want to set the default value of remoteID option same as the name of each
section. How to do it? I tried below code and get a result of table. 

local rid = s:option(Value, "remoteID", translate("Remote ID"))
rid.default = s.map:get(section,"name")

Cheers. 
Edwin
