eventData undefined after animate

[Bertilope]

I'm building a page with a list of posts for which i use flickable for infinite scroll. When a post is clicked i move the flickable down and load the single post through ajax. when i go back to the posts page i get an error in scrollSegment. For some strange reason eventData is undefined (error: can not read property end of undefined (methods.scrollToSegment)). I unbind, nullify the flickable, remove data attributes and then reinitialize flickable. To prevent the code from breaking i added this line of code:

eventData = eventData ? eventData : eventDataObject;
