Is there a way to Specify a OneWay Binding in HandleBars? bind-attr always calls Ember.bind, which always create a two way binding. This seems to be the case for elements that don't even change:

<img {{bind-attr class=":class-name-to-always-apply"}}>

But even in cases where the element could change, we might have reasons to update it manually (e.g. performance or we don't want to change it on textChanged, but do it manually)
