Ember + django @ How to send List of objects via ajax to backend?

I am using python&Django for backend.

How to send List format to the bakend via ajax

Any sort of help should be appreciable

EMBER

var data_payload = [{"title":"ember", "title":"ember-cli"}]

return ajax({
    url: 'here django server url',
    type: 'post',
    data: JSON.stringify(data_payload)
   }).then(function(output) {
       return output;
   });

DJANGO:

I am getting wrong format as below

{u'[{"title":"ember"},{"tile":"ember-cli"}]': u''}

The correct format should be like

[{"title":"ember"},{"tile":"ember-cli"}]
