angular is not evaluating my object when added dynamically on a input

1. You shouldn't be using {{ }} in the ng-model, you should write: ng-model="publisherParam.label"
2. You can't use expressions in the input's name, it needs to be a static string to support field-level validation.

If you could share a jsFiddle I would be happy to help more with the actual code.

It sounds like you want to use an ng-repeat, and $index to get the index of the item to put in the form input field's name. I'm not sure what exactly you're trying to do, but hopefully this puts you in the right direction...

EDIT: Also, the name="" of an input is irrelevant when submitting a form in Angular, as you can just take the entire object you're altering in $scope and send that via AJAX.

HTML

<form name="publisherForm" ng-submit="formSubmit()">
    <div class="inputbox" ng-repeat="publisherParam in publisherParams">
        <div>
            <label>{{publisherParam.label}}</label>
        </div>
        <div>
           <!-- use $index to get the index of the item in the array -->
           <!-- note, no {{}} inside of the ng-model tag. 
               That's being $eval'ed so no {{}} needed -->
            <input type="text" name="publisherParam_label_{{$index}}" ng-model="publisherParam.label" required />
        </div>
    </div>
    <!-- just an add button so you can see it work -->
    <button type="button" ng-click="addPublisherParam()">Add</button>
    <!-- your submit button -->
    <div class="submitbox">  
        <button class="purple-btn" type="submit ng-disabled="publisherForm.$invalid">
            Add Network
        </button>
    </div>
</form>

JS

app.controller('YourController', function($scope) {
   //this is the array you're displaying
   $scope.publisherParams = [
       { label: 'First Label' },
       { label: 'Second Label' }
   ];

   //just an indexer
   var p = 0;
   $scope.addPublisherParam = function(){
       //add a new publisher param.
       $scope.publisherParams.push({ label: 'New Label ' + p++ });
   };

   $scope.formSubmit = function(){
       //do something here.
   };
});
