How to binding an array in javaFx

Question

Hello fellows,
im trying to bind an array in javaFx but is not possible...
i have a problem that, in my point of view, only can be solved with a bind array.
a create some components in the scene dinamicaly and in other component (a button) a have to get this componets in the button function to manipulate them
this components that is dinamicaly created sofer some updates and can be deleted too.
i create an array that i put this components and my button recived this array, coz the array is always null (the inicial status of the array)
becouse of this i need a bindig array...
how can i do that?
or, that is an other solution?
i can get all the components in the scene of only one type (my component created dinamicaly)?

Here is example of a simple painter app where array binding is used:
import javafx.stage.*;
import javafx.scene.*;
import javafx.scene.paint.*;
import javafx.scene.input.*;
import javafx.scene.shape.*;
var elements: PathElement[];
Stage {
    title: "Simple Painter"
    scene: Scene {
        content: Group{
            content: [
                Rectangle{
                    width: 400
                    height: 300
                    fill: Color.WHITE
                    onMousePressed: function( e: MouseEvent ):Void {
                            insert MoveTo {x : e.x, y : e.y } into elements;
                    onMouseDragged: function( e: MouseEvent ):Void {
                            insert LineTo {x : e.x, y : e.y } into elements;
                Path{
                    stroke: Color.BLUE
                    elements: bind elements
}
