Ember.js Component properties data set by Ajax JSON - json

Question

I have a Component that has an injected service, which makes an Ajax call. I can receive the JSON data successfully and can dump it into the console after the promise "THEN" returns.
Here's my component. I can see the dumped data, but how do I set the component properties with that JSON and have it accessible in the template? Also, why can't I use "this.get" in my function below?
import Ember from 'ember';
export default Ember.Component.extend({
attr_types: Ember.inject.service('svc-attrtypes'),
atype_list: [],
actions: {
getATypes: function() {
this.get('attr_types').getTypes().then(function(json){
console.log(json);
this.atype_list = json;
console.log(this.atype_list);
// below returns: TypeError: this.get is not a function
this.get('atype_list').pushObjects(json);
});
}
}
});
In my template I have this:
{{#each atype_list.alltypes as |a|}}
<li>{{a.attr_type}} - {{a.attr_type_desc}}</li>
{{/each}}
If I manually place my JSON into the atype_list it shows perfectly on the template. But if I try to set it after my Ajax returns, nothing shows, except for in the console output.
I appreciate any help. I am sure I a missing something simple. ( or more likely, I'm just going about this all wrong)

This changed with anonymous function passed to then. You have to save this or use es6 arrow function syntax.
import Ember from 'ember';
const { service } = Ember.inject;
export default Ember.Component.extend({
attrTypes: service('svc-attrtypes'),
atypeList: [],
actions: {
// es6 version
getATypes(){
this.get('attrTypes').getTypes().then(array => {
this.set('atypeList', array); //replaces original array
this.get('atypeList').pushObjects(array); // adds array's elements to the end
});
}
// es5 version
getATypes: function () {
var _this = this;
this.get('attrTypes').getTypes().then(function(array){
_this.set('atypeList', array);
}
}
}
});
You wrote that you are new to ember, so I added little more syntax sugar. Also check ember-cli if you don't know about that already.
