[jQuery] Calling function through an event

[Vinyl]

I am using a slider and want to add labels to the slide/start event.
How can I call function from these events?

Something like this:

        $(function() {
                $("#slider").slider({
                        value:0,
                        min: 0,
                        max: 11,
                        step: 1,
                        slide: myFunction(ui.value);
                });
        });

       function myFunction(val){
        //
       }
