Inner element content change with pop-up

Hello @artf 

I've make pop-up for select custom link data with image. Now all the data reflected properly but when I try to change src than it's not working please let me know how to fix that. When input image URL in field 'Link Text(image URL)' than it should be update image in canvas. Please guide me.

This is live Demo: https://jsfiddle.net/gwojsok7/50
I've also console log the URL and this is in js section on line number 144

`save: function() {
            var attributes = data.component.get("attributes");
            attributes.href = this.getHref();
            attributes.title = this.title;
 data.component.set("attributes", attributes);
var image_url = this.content;
		console.log(image_url);
            data.component.view.render();
            editor.Modal.close();
          }`
