Intersecting Objects trigger not working when using Javascript to move character

I am using javascript in Storyline 360 to move an animated character on key press, which is working really well.  I would like to trigger a layer when the character intersects with certain portions or other objects of the scene. For some reason, adding an "Object intersect" trigger is not working. Below is a sample of the code I am using. This action moves the character to the left. Any suggestions would be helpful. 

var player = GetPlayer();

let bGirl = document.querySelector("[data-acc-text='BGirlStanding.gif']");
let bGirlMoveX = gsap.getProperty(bGirl, "x");
let bGirlMoveY = gsap.getProperty(bGirl, "y");

let maxWidth = player.GetVar("pgWidth");
let currentX = player.GetVar("bGirlX");

let maxHeight = player.GetVar("pgHeight");
let currentY = player.GetVar("bGirlY");

let moveY = (0);
let exit = (0);

if (currentX > 0)
{
moveX = (-100);
}
else
{
moveX = (0);
newExit = player.GetVar("exit");
player.SetVar("exit",newExit+1);
}

gsap.to( bGirl, { duration:0.25 ,x:bGirlMoveX+moveX,y:bGirlMoveY+moveY});player.SetVar("bGirlX",bGirlMoveX+moveX);
player.SetVar("bGirlY",bGirlMoveY+moveY);
