Disabling pinch zoom also disables scrolling


I have used this code to disable zoom in my app on pinch or double tap event but it also disables scrolling on the page


document.ontouchstart = function(event) {
		var touchEvent = event.changedTouches[0];
		if (touchEvent.pageX || touchEvent.pageY) {

			lastX = touchEvent.pageX;
			lastY = touchEvent.pageY;
			window.scrollTo(lastX, lastY);
