Variable binding with javafx.ext.swing.SwingSlider

Question

My first javafx program consists of a slider and a text box, the text box displays the current value of the slider. The problem is the text box does not display anything when the program just starts up, but only gets populated once I change the value of the slider. I am not sure what I am doing wrong. Here is the code:
import javafx.scene.control.*;
import javafx.scene.*;
import javafx.stage.*;
import  javafx.ext.swing.*;
import javafx.scene.layout.*;
var BPMSlider = SwingSlider {
    minimum: 10
    maximum: 250
    value: 60
}; //BPMSlider
var BPM = bind "{BPMSlider.value}";
var BPMDisplay = TextBox {
     text: bind BPM
    columns: 3
}; //BPMDisplay;
Stage  {
    title: "Slider";
    width: 1000
    height: 500
    visible: true
   // Set the scene
   scene:
       Scene {
       content:       
           HBox{ spacing: 10 content:[ BPMSlider, BPMDisplay ] }
       } // Scene
}Thanks!

Hi,
I don't know how to solve it with binding values, but I managed to solve it with temporary int value which contains Slider.value.
If any one can help us with solving this binding value we are waiting for answer.
Here is the code:
package slider;
import javafx.ext.swing.*;
import javafx.scene.*;
import javafx.scene.control.*;
import javafx.scene.input.MouseEvent;
import javafx.scene.layout.*;
import javafx.stage.*;
var tempSliderVal:Integer = 60; // temp BPMSlider value
var BPMSlider = SwingSlider {
    minimum: 10;
    maximum: 250;
    value: bind tempSliderVal with inverse;
    onMouseDragged: function (e:MouseEvent) {
        BPMDisplay.text = tempSliderVal.toString();
    onMouseClicked: function (e:MouseEvent) {
        BPMDisplay.text = tempSliderVal.toString();
}; //BPMSlider
var BPMDisplay = TextBox {
     text: tempSliderVal.toString();
    columns: 3;
}; //BPMDisplay;
Stage  {
    title: "Slider";
    width: 1000;
    height: 500;
    visible: true;
    // Set the scene
    scene: Scene {
        content: HBox{
            spacing: 10;
            content:[ BPMSlider, BPMDisplay ];
    } // Scene
}
