Please find code following

         //var e = (e.changedTouches != undefined)? touches[0] : e; 
         if(isMoving) {              
             var x = e.touches[0].pageX;
             var dx = startX - x;
             if(Math.abs(dx) >= config.min_move_x)
             {
                 if(config.preventDefaultEvents) { 
                     e.preventDefault();                 
                 }
                cancelTouch();
                if(dx > 0) {
                    config.wipeLeft();
                }
                else {
                    config.wipeRight();
                }
                return false;
            }
             else {
                   console.log('y moving.. ');
                   // attachTouch();
                    return true;
             }
         }

     }

Just adding some more details . I am trying to animate my list horizontal by BXslider and its works fine want to support the touch events so added the touch wipe jquery . But adding it give 1 issue that's horizontal scroll animation works ok but touch page vertical scroll not works.

So i tried to fixed issue by return true; if its only Y move, at touchwipe js. This fix working fine on android4 and ios5 but fails in ios6 if i scroll my page vertically little aggressively(moving finger in oval/circle for 4-5 sec) its freez bxslider animation.

further debugging give inside that bxslider.gotoNextSlide()-> calling the Jquery $parent.animate() method for sliding which stop working in ios6 after aggressive scroll.

Now i m stuck and not able to understand why this animate() stops working ??
