How can I use ng-click to dynamically reload ng-repeat data? - angularjs

Question

I have a page that contains an ng-repeat directive. The ng-repeat works when the page first loads, but I want to be able to use ng-click to refresh the contents of the ng-repeat. I have tried the following code but it doesn't work. Any suggestions?
<div ng-click="loadItems('1')">Load 1st set of items</div>
<div ng-click="loadItems('2')">Load 2nd set of items</div>
...
<table>
<tr ng-repeat="item in items">>
// stuff
</tr>
</table>
ItemsCtrl:
$scope.loadItems = function (setID) {
$http({
url: 'get-items/'+setID,
method: "POST"
})
.success(function (data, status, headers, config) {
$scope.items = data;
})
.error(function (data, status, headers, config) {
$scope.status = status;
});
};
I was hoping that my call to loadItems() would cause the ng-repeat directive to reload with the new data obtained from my server.

Add a broadcast in your callback and subscribe to it in your controller.
This should really be in a service btw
itemsService.loadItems = function (setID) {
$http({
url: 'get-items/'+setID,
method: "POST"
})
.success(function (data, status, headers, config) {
$scope.items = data;
$rootScope.$broadcast('updateItems', data);
})
.error(function (data, status, headers, config) {
$scope.status = status;
});
};
In your controller:
$scope.$on("updateItems",function(d){
$scope.items = d;
});
So whenever you ng-click="update(id)"
$scope.update = function(id){
itemsService.loadItems(id);
}
Your items will automatically update because it is subscribed.
