In order to declare a binding for an attribute, you'll need to use bindAttr . You can use this helper to bind an attribute either to a global path or to a variable in the current context, such as your view.

For instance, you might have a template like this:

<a {{bindAttr href="menuUrl"}}>Edit Selected Menu</a>

Which is bound to a property in your view, like this:

App.MyView = Ember.View.extend({
    menuUrl: function() {
        return "/Admin/MenuEdit/" + this.get("App.adminController.selectionMenu");
    }.property("App.adminController.selectionMenu)            
});

I created a fiddle for this example. ​
