   Binding notify problem with array binding

   
   
   
   

   
   

   Hi,
   

   I'm currently trying to use "bindTo" with "deep:true" on an object, which one of its property is an array.
   
   This will be more clear here:
   
   http://ift.tt/1zaAwQp

   
   

   Each click on a button must increments the label by 1. For the first button, which is bind to a number property on my objet, all works well.
   
   The second button is bind to an array which is a sub-property of my object. On click, the label is not updated, but the model inside is. If you click on the first button (and then implies a refresh), the second button label will be updated to the correct value.

   
   

   Am I doing something wrong or is there a real problem?
   
   Thank you!

   I find a workaround:
   
   http://ift.tt/1vCTlN4
   

   It seems that re-setting the same array (even with new or different elements) breaks the binding detection. The array have to be a new reference.
   
   Thus, changing this:
   

   
   

   
   

   Code:

   
   

   
   obj.bar[0] = obj.bar[0]+1;
   

   
   to this:
   
   

   
   

   Code:

   
   

   
   obj.bar[0] = obj.bar.slice()[0]+1;
   

   
   makes it work....
   

   I might be wrong, but I'm not sure it's the desired behaviour.
