Angular JS hidden field : saving ng-model with condition

Question

I have a hidden field, which is used to identify the category of the directive.

How can I bind the data as :

<input type = "hidden" ng-model="category = category.option.name == 'By Count Range' ? 'byCount' : 'byRate' ">

The above code is not assignable while compiling.

How can I solve this?

I'm not sure about my code, but I need to perform that condition check.

So, you have with two options: By count range or by rate and depending on which one is selected you want to change the . right?

Then, you can do this in template:

<select name='...' ng-model='...' ng-change='updateOptions()'>

and in your controller:

$scope.updateOptions = function () {
    if ($scope.category.priceOrTransactionOption == 'By Count Range'){
      $scope.categoryOptions = $scope.category.byCountRange.tiers
    }else{
      $scope.categoryOptions = $scope.category.byRate.tiers;
    }
};

and in html:

<div ng-repeat="categoryObject in categoryOptions track by $index">

<div>
