easeOutBounce - jQuery не знает такого метода анимации.

Вам нужно подключить библиотеку
jQuery UI effects.
Ответ кроется тут:
init: function( elem, options, prop, end, easing, unit ) {
this.elem = elem;
this.prop = prop;
this.easing = easing || jQuery.easing._default; // <-- параметр easing задан.
this.options = options;
this.start = this.now = this.cur();
this.end = end;
this.unit = unit || ( jQuery.cssNumber[ prop ] ? "" : "px" );
},
cur: function() {
var hooks = Tween.propHooks[ this.prop ];
return hooks && hooks.get ?
hooks.get( this ) :
Tween.propHooks._default.get( this );
},
run: function( percent ) {
var eased,
hooks = Tween.propHooks[ this.prop ];
if ( this.options.duration ) {
this.pos = eased = jQuery.easing[ this.easing ]( // <--- BREAK POINT HERE
percent, this.options.duration * percent, 0, 1, this.options.duration
);
} else {
this.pos = eased = percent;
}
