Ember-CLI - How to dynamically add component?

I am trying to add a new component dynamically using the following code:

var view = Ember.View.create({
    template: Ember.Handlebars.compile('{{image-upload}}')
});
Ember.run(function() {
    view.appendTo(document.body);
});

but I get the error:

Uncaught Error: Assertion Failed: You cannot append to an existing Ember.View. Consider using Ember.ContainerView instead.

Can someone point me in the right direction please?
