Angularjs, how to reset directive variables when button clicked in controller?

Question

First of all, I'm sorry to ask simple like below.

I have no code to show you.

Maybe this seems like a kind of rude question, but I expect somebody will give me some examples.

I've succeeded to link directive and controller.

I built modal like this link.

Add element dynamically by using Modal

In my original code, modal have a button to close itself.

What I want is when I click this button, all variables related with directive to be initialized.

But I don't know how.

Help me please. Thanks in advance for any help.

Why don't you use a service?? Just broadcast and catch the event in directive and reset your variable. — user8317956

Is this ng2? or the old one?. Use $scope.$broadcast('eventsomethingreset') then catch it on your directive $scope.$on('eventsomethingreset', func () { //reset stuff })' if ng1 else if ng2 use RxJS Observable — masterpreenz

ng-if will re-render the element to which it is applied

For Example

In html

<my-directive ng-if="reRender"></my-directive>

<button ng-click="resetDirective();">Reset Directive</button>

In Controller

$scope.reRender = true; //initial value

$scope.resetDirective = function(){
    $scope.reRender = false;
    var timer = $timeout(function(){
        $scope.reRender = true;
        $timeout.cancel(timer);
    }, 500);
}
