$index of Object in Array while using ng-repeat and a filter

Im fairly new to angular and have been able to get around somewhat. But I cant seem to find the answer to this scenario...

I have an array of objects, which I am pulling down from firebase. I am using an ng-repeat for the objects, then displaying data accordingly. I am trying to pass the index as a routeparam to an "edit" controller. In which case I would like to pull the object data as one would anticipate. However, when I filter the ng-repeat I am getting the index of the filtered content. where am I going wrong in finding the true index?

.config(['$routeProvider', '$locationProvider', function($routeProvider, $locationProvider) {
.when('/profiles/:index', {
templateUrl: '../views/profile.html',
controller: 'profileCtrl'

Route is above, Controller is below

.controller('profileCtrl', function( $scope, $routeParams ){

$scope.teamProfile = $scope.ourTeam[$routeParams.index];
$scope.index = $routeParams.index;

And finally the snippet of html from within the repeat.

<div class="profileName"><a href="/profiles/{{$index}}">{{}}</a><span class="handle">{{member.handle}}</span></div>


Unfortunately $index is only the "iterator offset of the repeated element (0..length-1)"

If you want the original index you would have to add that to your collection before filtering, or simply not filter the elements at all.

One possible approach:

angular.forEach(members, function(member, index){
   //Just add the index to your item
   member.index = index;

<div ng-repeat="member in members">
   <a href="/profiles/{{member.index}}">

Now, it also seems that this kind of information is really more like an ID than anything else. Hopefully that is already part of the record, and you can bind to that instead of using the index.
