Getting raw reponse after fetching backbone collection

I have an json response from the server like this for backbone collection

 {
       "Heading":[
          {
             "heading1":"heading1",
             "heading2":"heading2",
             "heading3":"heading3",
             "heading4":"heading4",
             "heading5":"heading5",
             "heading6":"heading6",
             "heading7":"heading7"
          }
       ],
       "Data":[
          {
             "column1":98310,
             "column2":"spl",
             "column3":"sreedhar Laptop",
             "column4":"LAPTOP",
             "column5":"ACTIVE",
             "column6":true,
             "column7":"c56e4b92-debe-4c8e-9472-bbb6a322346d"
          },
          {
             "column1":196609,
             "column2":"NLP",
             "column3":"NLP testing..",
             "column4":"LAPTOP",
             "column5":"ACTIVE",
             "column6":true,
             "column7":"7fe2efd4-b93b-4ea8-98a4-7a75d77efb77"
          },
          {
             "column1":262146,
             "column2":"venky",
             "column3":"venkyLaptop",
             "column4":"DESKTOP",
             "column5":"INACTIVE",
             "column6":false,
             "column7":"2e512b95-e2b3-414c-8b40-3bd00b626ae4"
          }
       ]
    }

So What I want is to pass only the Data aray for the collection so I have used parse method like this

Customer = Backbone.Collection.extend({
    model: customerModel,

    url: function () {

        return Config.serviceURL("getCusData");


    },
    parse: function (response) {

        return response.Data;
    }


});

This is working perfectly but Now I want that Heading array also after I apply fetch So how can I get this Heading array on calling fetch??

There's no rule that says that parse can't stash parts of response in this. For example:

parse: function(response) {
    this.headings = response.Heading;
    return response.Data;
}

Then later the collection can look at this.headings to see the response.Heading values.

If you're using other methods (such as reset) to populate your collection then you might need to override those to reset this.headings.
