Ember.js - ember-data - escaped /

I've a model and I use ember-data and inside the line export..., I've qr_code:DS.attr('string') and there're some slash in the qr code like "///"

And then my template I've this

I used triple {} and seems still escape or cutoff the data up to the first slash.

Any idea how I can show what the data it is and not cutoff the data or escapes it?
