How to get field value from the additional lookup fields?

Here's the example... I have a list, let's call it "The List". In The List I have a column called "The Column" and it's of Lookup type. The Column is a lookup to "The List2" list, particulary the Name field, but it also has additional field selected from the same list (The List2), ID field for example.

I have no problems selecting "The Column" field value on "The List" form
var TL2Name = fd.field('The_x0020_Column').control().value();

In the other hand, every time I try to read the value from  "The Column:ID"
var TL2ID = fd.field('The_x0020_Column_x003a_ID').control().value();
I get "undefined" value, although I'm using correct internal name.

Is there a way around this?
