You cannot modify child views while in the inBuffer state in ember

In my ember app(version 1.9.1 - EAK), I have something in a hbs file like,

{{#each obj.obj1}} 

 {{#view "selection" model = this}}
 ---------some code-------
 {{/view}}

{{/each}}

That's working fine. If I change it like this,

{{#each item in obj.obj1}} 

 {{#view "selection" model = this}}
 ---------some code-------
 {{/view}}

{{/each}}

am getting the error "You cannot modify child views while in the inBuffer state in ember".
