event triggers previous state attributes to remote storage

I'm trying to extract the change in src of an image and store it in the remote storage using Storage Manager, by using the following code

editor.on('stop:open-assets', model => {
    editor.StorageManager.get('remote').set({ 
      params: {
        metakey: 'logo-src',
        val:  editor.getSelected().attributes.src
        },
      },console.log("storage assets",editor.getSelected().attributes.src))
  })

The issue I'm facing is that when I change the image for the first time, it gives me the desired output in the console-> storage assets image2.jpg but the params are not affected, in fact no trigger it made to the params

The second time I change the image to to image1.jpg, i get the desired output in the console-> storage assets image1.jpg but the params affected contain values of the previous state and return image2.jpg

hence on, every time i change to a new image the params return the previous state. This behaviour is unusual. I didn't face an issue like these while dealing with other events
