backbone.js - When should I not use a self-rendering view? -

i've been studying this backbone tutorial , came across bit of code:

var libraryview = backbone.view.extend({     el:$("#books"),      initialize:function(){         this.collection = new library(books);         this.render();     },     ... }); 

the author explains this.render() makes view render when constructor called.

when not want view self-render?

the render method nothing more adding html dom using jquery's html or append methods. choose call render method on view architectural choice.

backbone said apply mv* pattern models bound directly view.
such, view render upon instantiation, , have ability render when model changes.

however, backbone leave lot of decisions developer , flexible library. there nothing technically prevents use control objects manage flow of views; such, object can instantiate , re-render view well.

var view = new bb_view();  view.render();  

in end, render method on view, , can define own methods well. example reason why call custom methods on view outside view, when keep reference array of views.
event occurs, loop through views, might add conditions, , call custom method on particular views based on condition.
