Display a list of items in Ember not working with each

I am trying to display a list of items in Ember.js but is not working and I don't get any error in the console. If I go to a specific element it works but I can't iterate the array.

  <h1> Forecast 16 days </h1>

  // this line works
  

  // this block doesn't work
  
     <div></div>
