Meteor+angular2 File Upload

I have copied the zip file from tutorial as is, after creating the upload images feature, and it doesnt show the small pictures near the file when uploaded, and also after uploading the first file, no matter what you upload after that it always showing and saving the only first file you uploaded.
by the way is there any example of meteor-angular2 + upload files to google storage/ s3 project?

Thanks,
Roi
