Updating Angular originally loaded via JSONP - angularjs

Question

I have a resource that returns a JSONP payload:
app.factory('JsonService', function($resource) {
return $resource('//123.456.7.890\\:8888/user/:id/:model',
{'page': ':page', 'limit' : ':limit', 'jsonp_callback' : 'JSON_CALLBACK'},
{})
});
Which gets called by my controller:
app.controller("followersCtrl", function ($scope, $dialog, JsonService) {
...
$scope.user_id = $.globals.authed_user_id;
$scope.model = "followers"
$scope.loadJSONP = function (getPage) {
JsonService.get({
id: $scope.user_id,
page: getPage,
limit: $scope.pagination_limit,
model: $scope.model
},
function (data) {
$scope.followers = data;
$scope.noOfPages = data.page_count;
$scope.currentPage = data.page;
});
};
$scope.loadJSONP(1);
$scope.pageChanged = function (page) {
$scope.callbackPage = page;
$scope.loadJSONP(page);
};
});
Then I loop over the data returned/stored in $scope.followers:
<div ng-controller="followersCtrl">
...
// Code related to the modal omitted
...
<div ng-repeat="user in followers.data">
<img class="img img-polaroid" ng-src="{{user.image_url}}"/>
<p>{{ user.username }}</p>
<button class="btn btn-disabled" ng-show="user.is_mutual">
You Are following this user
</button>
<button class="btn btn-primary" ng-show="!user.is_mutual">
You Aren\'t following
</button>
<p>{{user.total_followers}}</p>
</div>
...
// Code related to the modal omitted
...
</div>
That all works as expected, but for the life of me I cannot figure out how to have the "You are not following" button change the value that's reflected inside the corresponding {{post.total_followers}} expression on click. Ideally, I would like to perform a PUT to actually perform the follow action, but I decided to start small and just update the value, to no avail.
Any help is appreciated. Thank you.

Is ng-click what you're looking for?
HTML:
<button class="btn btn-primary" ng-show="!user.is_mutual" ng-click="follow(user)">
You Aren\'t following
</button>
JS:
app.controller("followersCtrl",
function ($scope, $dialog, JsonService) {
$scope.follow = function(user){
// code for posting to server-side follow action
// and updating the total_followers
// $scope.user.total_followers++; // this should be ideally incremented on success callback
}
}
);
