callback is allways called

Maybe I am getting something wrong, but this

``` coffee
if (!e.originalEvent.clickin || e.originalEvent.clickin !== id) {
```

will always evaluate to true, even if clickin has the same counter value. Since it is stored as an attribute it is a string.

This seems to work the way I understand it should:

``` coffee
if (!e.originalEvent.clickin || parseInt(e.originalEvent.clickin) !== id) {
```
