trigger action:post.toggleVote on client-cide

[josef]

hi,
I'm trying to do a client side script that eliminates dislike, apparently the shape is like this:

 $(window).trigger('action:post.toggleVote', {
    "pid": "501",
    "delta": -1,
    "unvote": true
});

But it does not work. In fact, I can not initiate any change in the voting of posts ...
What's wrong here?
