Fixed waypoint issue when scrolling back number doesn't count till the end

[flashblue]

I added the following code to store counter data. Because, after scrolling the page, the counter wasn't count till the stored number.

if ($this.data("text")==undefined) {
$this.data("text", $this.text());
} else {
$this.text($this.data("text"));
}

var num = $this.text();
