$('#someElm').bind('touchmove',function(e){
       e.preventDefault();
      var touch = e.originalEvent.touches[0] || e.originalEvent.changedTouches[0];
      var elm = $(this).offset();
      var x = touch.pageX - elm.left;
      var y = touch.pageY - elm.top;
      if(x < $(this).width() && x > 0){
          if(y < $(this).height() && y > 0){
                  //CODE GOES HERE
                  console.log(touch.pageY+' '+touch.pageX);
          }
      }
});
