I have 6 diffrent div, every div has 4 png. this divs in a slider. when slider init I'm enabling plax on number 1 div. when I slide to another div disable number 1 div and activate second div's plax. its working fine. but in ipad or iphone after few times disable/enable parallax stop working.

here is sample two function when change slide. Am I doing wrong?

thank you

function initSlideOne() {
$.plax.disable({ "clearLayers": true, "restorePositions": true });
$("#SlideOne img.layer1").plaxify({ "xRange": 0 });
$("#SlideOne img.layer2").plaxify({ "xRange": 100 });
$("#SlideOne img.layer3").plaxify({ "xRange": 130 });
$("#SlideOne img.layer4").plaxify({ "xRange": 100, "invert": true });
$("#SlideOne img.layer5").plaxify({ "xRange": 200, "invert": true });
$.plax.enable({ "activityTarget": $('#SlideOne') });
}

function initSlideTwo() {
$.plax.disable({ "clearLayers": true, "restorePositions": true });
$("#SlideTwo img.layer1").plaxify({ "xRange": 0 });
$("#SlideTwo img.layer2").plaxify({ "xRange": 100 });
$("#SlideTwo img.layer3").plaxify({ "xRange": 130 });
$("#SlideTwoe img.layer4").plaxify({ "xRange": 100, "invert": true });
$("#SlideTwo img.layer5").plaxify({ "xRange": 200, "invert": true });
$.plax.enable({ "activityTarget": $('#SlideTwo') });
}
