Converting CSS Sticky Plugin Into Angular Directive - angularjs

Question

I am trying to use this Sticky CSS plugin with an Angular Directive. I tried wrapping this code into a Directive but no luck yet getting it to work.
Here is the CodePen of the plugin without Angular - http://codepen.io/chrissp26/pen/gBrdo
and this is what I have so far.
Any help or guidance would be greatly appreciated.
app.directive('sticky', function() {
return function stickyTitles(stickies) {
this.load = function() {
stickies.each(function(){
var thisSticky = jQuery(this).wrap('<div class="followWrap" />');
thisSticky.parent().height(thisSticky.outerHeight());
jQuery.data(thisSticky[0], 'pos', thisSticky.offset().top);
});
}
this.scroll = function() {
stickies.each(function(i){
var thisSticky = jQuery(this),
nextSticky = stickies.eq(i+1),
prevSticky = stickies.eq(i-1),
pos = jQuery.data(thisSticky[0], 'pos');
if (pos <= jQuery(window).scrollTop()) {
thisSticky.addClass("fixed");
if (nextSticky.length > 0 && thisSticky.offset().top >= jQuery.data(nextSticky[0], 'pos') - thisSticky.outerHeight()) {
thisSticky.addClass("absolute").css("top", jQuery.data(nextSticky[0], 'pos') - thisSticky.outerHeight());
}
} else {
thisSticky.removeClass("fixed");
if (prevSticky.length > 0 && jQuery(window).scrollTop() <= jQuery.data(thisSticky[0], 'pos') - prevSticky.outerHeight()) {
prevSticky.removeClass("absolute").removeAttr("style");
}
}
});
}
}
return function(){
var newStickies = new stickyTitles(jQuery(".followMeBar"));
newStickies.load();
jQuery(window).on("scroll", function() {
newStickies.scroll();
});
};
});

try this:
<sticky>
<div class="followMeBar">a</div>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<div class="followMeBar">b</div>
</sticky>
directive:
app.directive('sticky', function() {
var stickyTitles = function (stickies) {
this.load = function() {
stickies.each(function() {
var thisSticky = jQuery(this).wrap('<div class="followWrap" />');
thisSticky.parent().height(thisSticky.outerHeight());
jQuery.data(thisSticky[0], 'pos', thisSticky.offset().top);
});
}
this.scroll = function() {
stickies.each(function(i) {
var thisSticky = jQuery(this),
nextSticky = stickies.eq(i + 1),
prevSticky = stickies.eq(i - 1),
pos = jQuery.data(thisSticky[0], 'pos');
if (pos <= jQuery(window).scrollTop()) {
thisSticky.addClass("fixed");
if (nextSticky.length > 0 && thisSticky.offset().top >= jQuery.data(nextSticky[0], 'pos') - thisSticky.outerHeight()) {
thisSticky.addClass("absolute").css("top", jQuery.data(nextSticky[0], 'pos') - thisSticky.outerHeight());
}
} else {
thisSticky.removeClass("fixed");
if (prevSticky.length > 0 && jQuery(window).scrollTop() <= jQuery.data(thisSticky[0], 'pos') - prevSticky.outerHeight()) {
prevSticky.removeClass("absolute").removeAttr("style");
}
}
});
}
}
return {
restrict: 'E',
link: function(scope, element, attrs) {
var newStickies = new stickyTitles($(element).find(".followMeBar"));
newStickies.load();
jQuery(window).on("scroll", function() {
newStickies.scroll();
});
}
};
