backbone.js - Listen to attribute changes in a backbone view -

-

I want to call a method in my view when its attributes Gives me an error: There is no undefined function . 

  SimpleView = Backbone.View.extend ({initialize: function () {this.attributes = _.extend (this.attributes, Backbone.Events); // update this.attributes.on ('change', this.updateAttributes (), this);}});   
  Update:  I thought I have  attributes  with  backbone.Events  so that I can hear the changes. Yes ... so now I do not get any more errors, but still nothing happens. Any help would be greatly appreciated.   
 
 
 Although I recommend you to use a model to keep attributes, If you want to be with the current perspective, then you have to manually trigger the event.  
  this.attributes.trigger ('change');   
 I have made your updates so that you can get an idea of ​​how it can work.

Use a stored procedure and specify the call statement on your query Perform...
