Nesting Views within Views in backbone js

Question

I'm working with backbone.js building some complex view relationships, and I'm wondering if there are any problems from a javascript performance standpoint of doing something that looks like this:

var viewOne = Backbone.View.extend({
         tagName : 'li',
         initialize : function() {
              this.v2 = new viewTwo({parent:this});
         },
         clickHideOne : function() {
              $(this.el).removeClass('selected');
         }
});

var viewTwo = Backbone.View.extend({
         tagName : 'a',
         initialize : function() {
              this.bind('click', this.clickHide, this);
         },
         clickHide(){
              $(this.el).removeClass('selected');
              this.options.parent.clickHideOne();
         }
});

Where this is a very simple example of a circular reference between two views, in order to have events in one view easily propagate up a chain of views, or maintain any references to objects in the parent views. Are there any situations where this would be a problem, specifically in relation to the potential leaks with DOM element references in IE7+, or is there another recommended best practice for referencing parent views.

Also, I understand that I could just do $(this.el).parent('li').removeClass('selected'); in viewTwo, that's not the point... this just a very simple example of the question I have about the circular reference.
