slickPrev and slickNext, only one is working

[pppws]

when using $slider.slick("slickPrev"); and $slider.slick("slickNext"); only one is working.

====================================================================

[ paste your jsfiddle link here ]

====================================================================

What is the expected behaviour?

when clicking on the left side of the screen i want to show the previous slide, when clicking on the right side i want to show the next slide.

====================================================================

What is observed behaviour?

only the first if-statement in the .js file is fulfilled. while the console outputs the right side (left = prev, right = next) the slideshow only processes the first statement, in this case always the previous slide.

This happens because you add the event listeners (for example when the mouse is on the left), but don't unregister them when the mouse moves to the right.

A better way would be this: http://jsfiddle.net/jc7fn34a/

For what it's worth, questions like this are better suited for StackOverflow, as they're not really an issue with the library.
