backbone.js - Backbone view in not rendering from collection.toJSON() -

-

i using backbone, handlebars, jquery app. following code line not working

this.$el.find('.quiz-container').append(quiz.tmplt.result(this.collection.tojson()));

template is

<h2 class="score">congratulation abcd! have scored {{score}} !!!</h2> <table>     <thead>         <tr>             <th>question</th>             <th>your answer</th>             <th>correct answer</th>         </tr>     </thead>     <tbody>         {{#each qtext}}         <tr>             <td>{{this}}</td>             <td>                 {{#each ../answer}}                 <span>{{this}}</span>                 {{/each}}             </td>                    </tr>         {{/each}}     </tbody> </table>

here json file

[{     "qid": "1001",     "qtext": "this question one?",     "options": [{"id":"opt1", "str":"15%"},{"id":"opt2", "str": "16%"},{"id":"opt3", "str": "17%"},{"id":"opt4", "str": "19%"}],     "answer": ["opt2"]},     {     "qid": "1002",     "qtext": "this question two?",     "options": [{"id":"opt1", "str":"item0"},{"id":"opt2", "str": "item1"},{"id":"opt3", "str": "item2"},{"id":"opt4", "str": "item3"}],     "answer": ["opt1"]},     {     "qid": "1003",     "qtext": "this question three?",     "options": [{"id":"opt1", "str":"5%"},{"id":"opt2", "str": "2.5%"},{"id":"opt3", "str": "11%"},{"id":"opt4", "str": "0%"}],     "answer": ["opt3"]} ]

i know, can split template , using collection.each method can render each object json file, want keep 1st template , render directly collection data.

thanks in advance
