Core Motion Module: Issue with isDeviceMotionAvailable() function

Hi community,

I'm trying to integrating ti.coremotion module in my Alloy app to create Image Gallery with tilt feature. Something like this widget by CaffeinaLab.

I'm getting the following error when try to load the image inside iPod/iPad device.

[ERROR] Script Error {
        backtrace = "#0 Controller() at file://.../UniversalApp.app/alloy/controllers/ImageGallerySlider.js:1\n#1 () at file://.../UniversalApp.app/alloy.js:1\n#2 t() at file://.../UniversalApp.app/alloy/controllers/ImageGallerySection.js:1";
        line = 1;
        message = "'undefined' is not a function (evaluating 'd.isDeviceMotionAvailable()')";
        name = TypeError;
        sourceId = 58346400;
        sourceURL = "file://.../UniversalApp.app/alloy/controllers/ImageGallerySliderImage.js";
    }

var CoreMotion = require('ti.coremotion');
 
if (CoreMotion && CoreMotion.isDeviceMotionAvailable()) {
    CoreMotion.setDeviceMotionUpdateInterval(4);
 
    CoreMotion.startDeviceMotionUpdates(function(e) {
        // logic goes here..
    });
    }
    else {
        Ti.API.error("CoreMotion not available");
    }

Technical details:

• Titanium SDK: 3.2.3.GA
• Alloy version: 1.3.1
• Device: iPod & iPad (iOS 7.1)
