I have 5 fixed Textbox, I have a JSON Array which should be bind with Textbox. 0th index element will be bind with 1st textbox.
<input type="text" class="form-control col-md-5" ng-model="jsonArray[0].amount">
In controller you assign to a variable and bind it,
Controller
$scope.amount = jsonArray[0].amount;
HTML
<input type="text" class="form-control col-md-5" ng-model="amount">
