Does anyone know which event is fired after a view is rendered in backbone.js?
I realise this question is fairly old but I wanted a solution that allowed the same custom function to be called after every call to render, so came up with the following...
First, override the default Backbone render function:
var render = Backbone.View.prototype.render;
Backbone.View.prototype.render = function() {
    this.customRender();
    afterPageRender();
    render();
};
The above code calls customRender on the view, then a generic custom function (afterPageRender), then the original Backbone render function.
Then in my views, I replaced all instances of render functions with customRender:
initialize: function() {
    this.listenTo(this.model, 'sync', this.render);
    this.model.fetch();
},
customRender: function() {
    // ... do what you usually do in render()
}
