Each `customButton` entry accepts the following properties:

## Events

You can define callbacks in `callbacks` option. In each callback you can get the `Magnify` instance with `this` or `context`.

```js
$("[data-magnify=gallery]").magnify({
callbacks: {
beforeOpen: function (context) {
// Will fire before modal is opened
},
opened: function (context) {
// Will fire after modal is opened
},
beforeClose: function (context) {
// Will fire before modal is closed
},
closed: function (context) {
// Will fire after modal is closed
},
beforeChange: function (context, index) {
// Will fire before image is changed
// The argument index is the current image index of image group
},
changed: function (context, index) {
// Will fire after image is changed
// The argument index is the next image index of image group
},
},
});
```
