Using isn't rendering an image in ember.js 2

I am using Ember.js andI am having an issue getting this piece of code to render out a logo.

<span data-src="/images/logo.png"></span>

Does Ember.js not allow the use of data-src? I have gone through the docs and I havent seen anything that alludes to this.

Sort of a beginner so bare with me.

Thanks! Derek
