Javascript / vue.js receive json

Question

I'm trying to receive json in my vue.js app like this:

  new Vue({
            el: 'body',
            data:{
                role: '',
                company: '',
                list:[],
                created: function() {
                  this.getJson();
                },
                methods: {
                    getJson: function(){
                        $.getJSON('http://domain.dev/data',function(task){
                          this.list = task;
                        }.bind(this));
                    }
                }
            }
        });

But the result is null? When I test this in postman the url returns json. What am I doing wrong here?

EDIT:

Building on @vbarbarosh's answer, but using the browser's fetch api:

a.json:

{"hello": "welcome"}

index.html:

<div id="app">
    <pre>{{ json.hello }}</pre>
</div>

<script type="text/javascript">
new Vue({
    el: '#app',
    data: {
        json: null
    },
    created: function () {
      fetch("/a.json")
        .then(r => r.json())
        .then(json => {
          this.json=json;
        });
    }
});
</script>

Here is a little example of how to load external JSON data into your component:

a.json:

{"hello": "welcome"}

index.html:

<div id="app">
    <pre>{{ json.hello }}</pre>
</div>

<script type="text/javascript">
var app = new Vue({
    el: '#app',
    data: {
        json: null
    }
});
$.getJSON('http://localhost/a.json', function (json) {
    app.json = json;
});
</script>

--- Edited ---

Or with created event:

<script type="text/javascript">
new Vue({
    el: '#app',
    data: {
        json: null
    },
    created: function () {
        var _this = this;
        $.getJSON('http://localhost/a.json', function (json) {
            _this.json = json;
        });
    }
});
</script>
