If you code like this, when the template is processed to generate web page
to browser, the code
luci.sys.call("env -i chilli_query logoff mac")
will be run at that time, and if it returns "AA:AA:BB:CC" for example, the
web page which your browser receives will be like this:

onclick="AA:AA:BB:CC
this.form.cbi_state='del-section'; return true"

What you need to do is to create a new view, at a URL
/deladdress
for example

and your JS code, after collecting MAC Addr/IP Addr will send an Ajax
request to that URL,
/deladdress?mac=aa:bb:cc
for example
And you have to code the view for /deladdress so that it get the value of
"mac" variable, then build a Luci call
For example:
local mac = form['mac']
local command = "env -i chilli_query logoff " + mac
luci.sys.call(command)

Note:
The form['mac'] should be checked again. I don't remember how to get HTTP
GET/POST data in LuCI
