[Kotlin UI DSL] Data binding does not work when the UI is being displayed

I wrote a dialog box and the code looks like this:

fun frame(data: FrameData) = panel {
    row(Constant.uiBundle.getString("label_language")) {
        cell {
            buttonGroup {
                radio("Java", Language.JAVA) { data.language1 = it }
                radio("Kotlin", Language.KOTLIN) { data.language1 = it }
            }
        }
    }

    row("Data binding)Language: ") {
        cell {
            buttonGroup(data::language) {
                radioButton("Java", Language.JAVA)
                radioButton("Kotlin", Language.KOTLIN)
            }
        }
    }

    row("Data binding)Desc: ") {
        textField(data::desc)
    }

    row {
        button("data") {
            Messages.showInfoMessage(data.toString(), "Info")
        }
    }
}

data class FrameData(
    var language: Language = Language.UNKNOWN,
    var language1: Language = Language.UNKNOWN,
    var desc: String = ""
)

Radio is a components that I wrapped myself in order to trigger an event when the value changes and manually modify the value of the data property

fun <T> Cell.radio(text: String, value: T, init: (JBRadioButton) -> Unit, selected: (T) -> Unit): CellBuilder<JBRadioButton> {
    val radio = JBRadioButton(text).apply {
        init(this)
        addItemListener {
            if (it.stateChange == ItemEvent.SELECTED) {
                selected(value)
            }
        }
    }
    return radio()
}

RadioButton and textField are components that come with the Kotlin UI DSL and use property binding

The panel returned by the frame method will be used by DialogConstructor, a subclass of DialogWrapper (custom implementation of text and events for the custom dialog OK and Cancel buttons).

When I click on the button named "data", I can see that the values of the language and desc properties of data are always the default values, and they are assigned only after I close the dialog

I need to get the latest data property values in real time, is there any way to do that?
