How to get value out of bound textfield in tableview?

Question

It seems I cannot find a solution how to get value out of a textfield in tableview. Hope I can describe my problem accordingly. Here are two pictures of my setup in IB:

I have subclassed NSTextField in order to draw a new background. This is working so far. But coming to the challenge to get the cells value as a variable, I can´t find a solution. The cell is getting it´s value out of a NSArrayController binding. I tried with self.objectValue, self.stringValue I´m always getting nil. Making an outlet is not possible as well.

Here´s the code of my subclass:

class ProgressView: NSTextField {

    func getOwnValue() {

        // Here I´m getting always nil
        let ownValue = self.objectValue
        let ownValue2 = self.stringValue

    }

}

What am I missing? Help would be much appreciated.

found the solution:

override var stringValue: String {
        didSet {
           Swift.print(stringValue)
        }
}
