How to muted video in Ember JS

I am newbie in Ember.JS. Below is the code in one hbs file.

     
          <img src=''>
     
          <video width="100%" height="100%" muted autoplay wrap controls>
            <source src=>
          </video>
     

I want to mute the video, I added muted in video tag. But it doesn't work. How I can I mute the video in Ember JS?
