I have a requirement to use carousel in one of my project. Recently we migrated from ExtJS4.2.1 to ExtJS5 The example shown here is working absolutely fine with ExtJS4.2.1 but when I use it with ExtJS5 it gives the error: "Ext.util.Observable#addEvents" is deprecated."
Can someone update the code or point out the error? Here is the code:

}
, initComponent: function () {
var me = this;
me.addEvents('carouselchange');
me.callParent(arguments);
}

var me = this;
me.drag = false;
var children = me.items.items;
var parentLeft = me.ownerCt.el.getLeft();
var rule = 1000000;
var target;
Ext.each(children, function (div, i) {
l = Math.abs(div.el.getLeft() - parentLeft);
if (l < rule) {
rule = l;
target = div;
};
});
me.showChild(target);
}
, onMousedown: function (e) {
e.stopEvent(); // prevents selecting the underlying text and whatnot
var me = this;
me.drag = true;
me.startX = e.getX();
var par = me.el.first();
par.on({
mousemove: function (e) {
e.stopEvent(); // prevents selecting the underlying text and whatnot

Remove this line:
me.addEvents('carouselchange');
addEvents has been deprecated in Ext JS 5.0 and will raise an error when used. Don't use it.
