Store binded object before change

I have an object which contains information on a group:

selectedGroup:  { 
      name: Test Group,
      id: 10,
      description: a group,
      owner: 88,
      ownerIsUser: False

I have textbox which binds to the property. I need to store that name in it's own variable before a change occurs.

I have an AJAX library that allows me to update the groups info like name and description but it needs the old name to identify which group to update. I tried:

var oldName =

But this doesn't work since as soon as I start typing something oldName gets updated.


You can create a watch:

$scope.$watch('', function(newVal, oldVal) {
   // save/copy oldVal somewhere 

PD: To deep copy the object you can use angular.copy()
