view-action id request

Someone knows how request an id from a table, with custom-table-fields.js

 

In EMONCMS I see code like this used a lot:

'view-action':{'title':'', 'type':"iconlink", 'link':path+"vis/auto?feedid="}

view-action':{'title':'', 'type':"iconlink", 'link':path+"dashboard/view?id="}

 

But if I make my table from the input data and only need to know what the id is in the first column of my new table. How do I do that?

I have tried this:

'view-action':{'title':'', 'type':"iconlink", 'link':path+"mytable/?nodeid="}

but the response is:
http://mi_ip/emoncms/mytable/?nodeid=undefined

I am missing something, but what?
