Listen to any change in the canvas

Actually I think there is an event that could serve this purpose. Could you try defining your method callback on 'change:changesCount'?

grapesjs\src\editor\model\Editor.js:64 this.on('change:changesCount', this.updateChanges, this);

I'm not sure if there's one exclusive event that listens for any changes to the canvas. Perhaps you could have your method run on all of the canvas events instead?

https://github.com/artf/grapesjs/blob/dev/src/editor/index.js#L53 `* ## Canvas

• • canvas:dragenter - When something is dragged inside the canvas, DataTransfer instance passed as an argument
• • canvas:dragover - When something is dragging on canvas, DataTransfer instance passed as an argument
• • canvas:drop - Something is dropped in canvas, DataTransfer instance and the dropped model are passed as arguments
• • canvas:dragend - When a drag operation is ended, DataTransfer instance passed as an argument
• • canvas:dragdata - On any dataTransfer parse, DataTransfer instance and the result are passed as arguments.`

@IStirton10 Let me try it out.I guess this should work.
