Changing tagName for a component

5

thanks for your reply @jthoburn.

Definitely, this approach was too complex, so I made the chart component to insert an html tag, when no data was retrieved from the server.

didInsertElement: function() {
    var _this = this;

    Ember.RSVP.Promise.resolve(this.get('data')).then(function(data){
        var parentDiv;
        if (data) {
          _this.setupChart(data);
        } else {
          parentDiv = $(_this.get('element')).parent();
          parentDiv.append('<div class="no-chart-data">No Chart data</div>');
        }   
    }); 
  },
