How to call another file with help of JSON in ember?

        **jsonfile:**
        {
        "themingtests":[  
              {  
              "id"  :1,
              "path": "EmberTest/WebContent/json/themingtests.json"
              }
           ]
         }

    **HTML file:**
    <script type="text/x-handlebars" id="index">
        {{#each item in model}}
    {{item.path}}
    {{/each}}

**JS File:**
App.Themingtest =DS.Model.extend({
    path: DS.attr('string'),

});

I'm not able to read a file on that particular path . Is there any other way then kindly please Suggest !!
