I'm trying to write some application using ng-repeat and limitTo, but it seems that the input field and the buttons can't work together on the same model value.
The problem is that once I changed the value from the input field, the buttons won't work any more. could you tell me why?
angular.module('myApp', []).controller('namesCtrl', function($scope) {
$scope.names = [
'Jani',
'Carl',
'Margareth',
'Hege',
'Joe',
'Gustav',
'Birgit',
'Mary',
'Kai'
];
$scope.test = 3;
$scope.dPlus = function(){
$scope.test++;
}
$scope.dMinus = function(){
$scope.test--;
}
});<!DOCTYPE html>
