Not working for body style tag

[shadysamir]

I am using the plugin to monitor my body tag if it gets a style="margin-top: 20px" attribute added to it. My code is as follows:

$('body').attrchange({
    trackValues: false, callback: function(e) {
    setHeroSize();
  }
});

It's never called even though the style attribute gets changed

Somehow it just worked now!
