The referenced ECMAScript file:


btnHeightInc.onclick = HeightIncrease();
btnHeightDec.onclick = HeightDescrease();
btnWidthInc.onclick = WidthIncrease();
btnWidthDec.onclick = WidthDecrease();


Are you sure that you want to call these methods here? You should remove the () from these if you want to assign the functions as the onclick event handlers.
