SUMMARY
I have a list of brands and a list of products. I am using an ng-repeat to show the list of brands, and an ng-repeat with a filter to show the list of products within their respective brands. I want each brand and each product to have a button that shows more about that brand/product. All of these buttons should use the same function on the controller.
PROBLEM
The button that shows more about the brand also shows more about each of that brand's products, UNLESS (this is the weird part to me) I click the button of a product within that brand first, in which case it will work correctly.
CODE
Please see the Plunker here, and note that when you click on 'show type' on a brand, it also shows all the types of the products within that brand: http://plnkr.co/edit/gFnq3O3f0YYmBAB6dcwe?p=preview

JAVASCRIPT
var app = angular.module('myApp', []);
app.controller('MyController', function($scope) {
$scope.brands = [{
name: 'Kewl',
type: 'Cereal'
}, {
name: 'Joku',
type: 'Toy'
}, {
name: 'Loko',
type: 'Couch'
}]
$scope.products = [{
name: 'Kewlio',
type: 'Sugar Cereal',
brand: 'Kewl'
}, {
name: 'Kewliano',
type: 'Healthy Cereal',
brand: 'Kewl'
}, {
name: 'Jokurino',
type: 'Rattle',
brand: 'Joku'
}, {
name: 'Lokonoko',
type: 'Recliner',
brand: 'Loko'
}, {
name: 'Lokoboko',
type: 'Love Seat',
brand: 'Loko'
}]
$scope.showType = function(item) {
this.show = !this.show;
}
$scope.filterProducts = function(brand) {
return function(value) {
if(brand) {
return value.brand === brand;
} else {
return true;
}
}
}
});
IMPORTANT NOTE: I realize I could add an attribute to the object (brand.show) and pass the object into the function, then change that attribute to true/false, but I don't want to do this because in my actual application, the button will show a form that edits the brand/product and submits the info to Firebase, and I don't want the object to have a 'show' attribute on it. I would rather not have to delete the 'show' attribute every time I want to edit the info in Firebase.
