Trying to add a child to another object, but it isn't moving with the parent!

I am trying to get structure to be glued to cobblestone ground! So that their X values are dependent!

However cobblestone ground just stays in the same place(on the screen, setViewportX doesn't do anythin!)

function Background() {

var texture = PIXI.Texture.fromImage("cobblestone_ground.png");

PIXI.TilingSprite.call(this, texture, 4000, 100);

this.position.x = 0;

this.position.y = 370;

this.tilePosition.x = 50;

this.tilePosition.y = 0 ;

this.viewportX = 1000;

var structure = new PIXI.Sprite(PIXI.Texture.fromImage("spire.png"));

structure.position.y = -100;

this.addChild(structure);

};

I don't know what "setViewportX" will do so I can't tell you, but changing "Background" position should seem to move the structure since it is a child of Background.

 

If not, show me an example that doesn't work an I can look into it.
