Rendering Ember component (google line chart) with rails backend

Question

Recently I started a project with rails backend and ember js, however I find the documentation on both together is difficult to find or quite ambiguous, however I have parts of my app working perfectly.

Now, I decided to code a google line chart in an ember component. With ember inspector, it tends to throw an error on localhost:3000/#/chart currently the error:

Uncaught Error: <Sample.ChartView:ember526> Handlebars error: Could not find property 'chart' on object (generated chart controller)

So, here's my code for the relevant files:

assets/javascript/components/chart_component.js :

var data = {
  labels : ["January","February","March","April","May","June","July"],
  datasets : [
    {
      fillColor : "rgba(220,220,220,0.5)",
      strokeColor : "rgba(220,220,220,1)",
      pointColor : "rgba(220,220,220,1)",
      pointStrokeColor : "#fff",
      data : [51,10,18,58,65,95,87]
    },
    {
      fillColor : "rgba(151,187,205,0.5)",
      strokeColor : "rgba(151,187,205,1)",
      pointColor : "rgba(151,187,205,1)",
      pointStrokeColor : "#fff",
      data : [28,48,40,19,96,27,100]
    }
  ]
};

var data2 = {
  labels : ["January","February","March","April","May","June","July"],
  datasets : [
    {
      fillColor : "rgba(220,220,220,0.5)",
      strokeColor : "rgba(220,220,220,1)",
      pointColor : "rgba(220,220,220,1)",
      pointStrokeColor : "#fff",
      data : [51,10,18,58,65,95,87]
    },
    {
      fillColor : "rgba(151,187,205,0.5)",
      strokeColor : "rgba(151,187,205,1)",
      pointColor : "rgba(151,187,205,1)",
      pointStrokeColor : "#fff",
      data : [28,48,40,19,96,27,100]
    }
  ]
};

Sample.LineChartComponent = Ember.Component.extend({
  tagName: 'canvas',
  attributeBindings: ['width', 'height'],
  width: '480',
  height: '360',
  data: null,
  didInsertElement: function() {
    var ctx = this.get('element').getContext("2d");
    var myNewChart = new Chart(ctx).Line(this.get('data'));
  }
});

javascripts/routes/chart_route :

Sample.ChartRoute = Ember.Route.extend({
  model: function(){
    return Ember.Object.create({
      modelOne: data,
      modelTwo: data2
   });
  }
});

Where I'm calling the chart component.. javascripts/templates/chart.handlebars

<h2>Chart one</h2>

{{chart data= model.modelOne}}

<h2>Chart two</h2>
{{chart data= model.modelTwo}}

As for the naming convention:

Components must have a dash in their name. So blog-post is an acceptable name, but post is not. This prevents clashes with current or future HTML element names, and ensures Ember picks up the components automatically.

As far as I see, you called your component simply "charts", that might be the problem.
