ScalaFX. Label - How to bind IntegerProperty?

I have a simple form for example:

object Main extends JFXApp {
    stage = new PrimaryStage() {
        title = "My Form"
        scene = new Scene {
            root = new Label { text <== ViewModel.intProp }
        }
    }
}

And a simple example ViewModel:

object ViewModel {
  //Some mutable integer property. I want to keep it as IntegerProperty, not StringProperty
  val intProp = IntegerProperty(10)

  intProp.value = 15
}

How to bind my IntegerProperty to my Label, which expects StringProperty?

Edited: I was forgetting about .asString. Doh!

You can simply bind the property as follows:

Main.scala:

object Main extends JFXApp {
  stage = new PrimaryStage() {
    title = "My Form"
    scene = new Scene {

      // Bind label to int property as a string.
      root = new Label {
        text <== ViewModel.intProp.asString
      }
    }
  }
}

ViewModel.scala:

object ViewModel {
  val intProp = IntegerProperty(10)

  intProp.value = 15
}
