AngularJS ng-click not working in <li> tag

Question

I'm making a pagination list image using AngularJS. ng-click doesn't work when I use it in <li> tag or even on <a> tag in it. But it's working fine in <button> tag.

<div  ng-controller="sampleCtrl" ng-app="myApp" data-ng-init="currentpage=1">
            <h2>{{currentpage}}</h2>
        <ul>
             <li data-ng-repeat="image in images[currentpage-1]">
                <img src='{{ image.img }}' width="150px" height="88px"/>
             </li>
        </ul>


    <ul class="pagination">
        <li data-ng-repeat="i in [1,2,3,4,5]" title="Page {{i}}">
            <a href="#" data-ng-click="currentpage = currentpage + 1">{{i}}</a>
        </li>
    </ul>
    <button data-ng-click="currentpage = currentpage + 1">Click me!</button>

</div>

Anyone knows what's the problem?

BTW, I tried this answer, but it's not working.

Answer 1

It's because ng-repeat creates a new scope for each repeated element. And when you're doing currentpage = currentpage + 1, you're most probably creating a new variable inside a child scope.

Check your scopes. The solutions is usually something as simple as $parent.currentpage = $parent.currentpage + 1 (to address the currentpage variable in the parent scope, the sampleCtrl scope) if you don't want to rewrite the whole thing.

Another solution would be creating a function to increase the page number, that way you won't be creating any new child scope variables, but would inherit the increase function from the controller:

<a href="#" data-ng-click="increasePage()">{{i}}</a>

And in your controller something like this:

$scope.increasePage = function() {
     currentpage++;
}
