ember install ember-mutation-observer-modifier
This addon provides an Ember [modifier][ember-modifier] for attaching a [MutationObserver][mutation-observer] to an element in your Ember template and calling an action when the observer fires. All configuration options supported by MutationObserver#observe are supported through the modifier.
In the following example, this.onChange will be called any time that this.someAttrValue is changed on the div, by observing the changes to the some-attr attribute.
`handlebars`
Note that options for the MutationObserver can also be provided as the second positional parameter to the modifier.
`handlebars`
Please consult the documentation for [MutationObserverInit`][mutation-observer-init] for a full list of supported parameters.
