I am using the view
helper multiple times, in order to render the same template but with different parameters every time, mostly booleans acting as option flags
You are overriding the init() method of Ember.View and not calling this._super(). This causes the view to not initialize properly resulting in your view elements missing id attributes (e.g. id="ember224").
Below is a link to your original JSBin with the addition of MyCustomView.init() calling this._super(). You will find the view elements now have id attributes.
