Adobe Animate CC JavaScript Code Causing Double Clicking In Mobile

I was told to place this code into Adobe Animate in order to allow mousedown and clicks to work for mobile:

// Enable touch events while allowing the touch events to bubble up to the document.

createjs.Touch.enable( stage, false, true );

// Don't let the stage to automatically prevent default touch events.

stage.preventSelection = false;

This is a sample event listener:

this.HoldChBx.addEventListener("click", CheckBoxClickHandler.bind(this,"Hold"));

The problem is that when I press a button in mobile, it actually double clicks. For example, I have a checkbox. I click for the check to show, but then another click happens again automatically to make the check go away. I don't know why this is happening. I don't have this problem when I try it on my desktop using a mouse. This is bizarre.

I am need stage.preventSelection = false so that the user can still zoom in and out using pinch.
