ng-repeat creates a child scope, item is passed to the child scope as a primitive type. even you isolates the scope in your directive with 2-way binding for value, the value will not be changed, ie. scope.items is always [1, 2]

solution is to pass an object (reference) to child scope, to achieve this:

$scope.items = []
$scope.items.push({val:1});
$scope.items.push({val:2});

// template of counter directive
<input type="text" class="counter-field" ng-model="value.val">

var setValue = function( val ) {
    scope.value.val = parseInt( val );
};

you might also need to change minus and plus methods to refer to scope.value.val
