How to dinamically set the limit in the controller with a ng-click function? <code>selectionLimit: dinamically ?</code>
<hr>
<button ng-click="updateMultiSelectLimit()">Update dropdown limit(doesn't work)</button>
<button ng-click="updateData()">Update dropdown data(do work!)</button>
<hr>
<p>Dropdown</p>
<div ng-dropdown-multiselect=""
options="example65data"
selected-model="example65model"
extra-settings="example65settings"></div>
</div>
</body>

// Code goes here
var myApp = angular.module("myApp", ['angularjs-dropdown-multiselect']);
myApp.controller("MyController", ["$scope", function($scope) {
$scope.message = "Angularjs-multiselect-dropdown";
$scope.example65model = [{id: 1}];
$scope.example65data = [{id: 1, label: "David"}, {id: 2, label: "Jhon"}];
$scope.example65settings = {selectionLimit: 3};
$scope.updateMultiSelectLimit = function (){
$scope.example65settings = {selectionLimit: 2};
}
$scope.updateData = function(){
$scope.example65data = [{id: 1, label: "Peter"}, {id: 2, label: "Yiss"}, {id: 3, label: "Max"}];
}
}]);

How can I update the dropdown setting(extra-settings) like the options(example65data)?
options="example65data"
selected-model="example65model"
extra-settings="example65settings"
