How to update the position of images on Canvas?

Question

JavaScript

Hello. Wrote a function to assign image positions on the canvas.
app.js (game)

my_Doge = game.addSprite("Doge", "mydoggy", 0, 700, 100, 100);

When an object is added, it is written to the array this.addedSprites
Library.js
this.addedSprites.push(spriteObj);
I also wrote a way to change the position for it

game.setPos(my_Doge, my_Doge.xcoord+=2, my_Doge.ycoord);

After changing the position in the library, the render method occurs

GameWindow.prototype.setPos = function(sprite, newX, newY)
{ // Set new sprite position
  sprite.xcoord = newX;
  sprite.ycoord = newY;

  for(var i = 0; i < this.addedSprites.length; i++)
  {
    if(sprite.id == this.addedSprites[i].id)
    {
      this.addedSprites[i].xcoord = newX;
      this.addedSprites[i].ycoord = newY;
    }
  }

  this.render(sprite, sprite.width, sprite.height, sprite.xcoord, sprite.ycoord);
}

GameWindow.prototype.render = function(sprite, width, height, x, y)
{
  ctx = this.ctx;

    canvas.width=canvas.width;

    ctx.drawImage(sprite, x, y, width, height);

}

Here's what happens:

If you remove the method

game.setPos(my_Doge, my_Doge.xcoord+=2, my_Doge.ycoord);

(so that the dog does not move), you can see. that I added a cat before, but it disappears, and only the dog is updated.

Okay, I tried the following thing - so that all objects from the array of added objects are this.addedSpritesalso drawn to the canvas by looping

gameWindow.prototype.render = function(sprite, width, height, x, y)
{
  ctx = this.ctx;

    canvas.width=canvas.width;

    for(var i = 0; i < this.addedSprites.length; i++)
    {
    	var w = new Image();
    	w.src = this.addedSprites[i].src;
    	ctx.drawImage(w, this.addedSprites[i].x,this.addedSprites[i].y,this.addedSprites[i].width,this.addedSprites[i].height);
    }

    ctx.drawImage(sprite, x, y, width, height);

}

but it didn't work out very well:

What's the problem? I do not understand how to make only other objects appear, and not the main character, who is already moving? Maybe the problem is in the render method?
Thank you very much
P.S
If you register movement for two objects, and not just for one

game.setPos(my_Doge, my_Doge.xcoord+=2, my_Doge.ycoord);
  game.setPos(my_Cat, my_Cat.xcoord+=2, my_Cat.ycoord);

Then only the one that is registered last will move
