Select using ng-option is not updating model in controller

I have the following array:
[{
"Id": 3,
"Name": "A"
},
{
"Id": 3,
"Name": "B"
},
{
"Id": 3,
"Name": "C"
}]
I am using this in the following Angular view:
<select ng-model="selectedCategory" ng-options="category.Name for category in categories"></select>
<pre>{{selectedCategory | json}}</pre>
<button type="button" ng-click="move()">Move</button>
The controller looks like:
var moveCategoryController = function ($scope, category, categoriesService) {
var getCategories = function () {
categoriesService.getCategories()
.success(function (result) {
$scope.categories = [];
for (var i = 0; i < result.Results.length; i++) {
var cat = result.Results[i];
if (cat.Id !== category.Id) {
$scope.categories.push(cat);
}
}
$scope.selectedCategory = $scope.categories[0];
})
.error(function () {
$scope.errorMessage = "There was a problem loading the categories.";
});
};
getCategories();
$scope.move = function () {
alert($scope.selectedCategory.Name);
};
}
bpApp.controller("moveCategoryController", moveCategoryController);
For info, the category object injected into the controller is a category object (the controller is being used in a modal and the category is passed to it from the parent page).
The Problem
On loading, the select is bound to the data fine, and when the user changes the select list the <pre> content updates correctly with the newly selected category.
The problem is when I click the Move button, which calls the move() function on the controller scope, the selectedCategory property of the scope has not been updated. For example, if I select the category "B", the alert still pops up with "A".
So, it seems that the ng-model is updated in the view, but not in the controller?!

Use the value of a variable to find an item in array

I am still having trouble using the var to identify the object in the array. Here is what I have right now:
in controller:
$scope.allbooks=[
{book1={title:"Eat Pray Love", price:"$3.99"},
{book2={title:"DaVinci Code", price:"$7.99"}}
]
$scope.pick=function(name){
$rootScope.choice = name;
}
in html template
<ion-item ng-click="pick(book1)">
{{allbooks.choice[0].title}} <----This does not work
Used an alert to make sure choice=book1 which it does...I don't know what I am doing wrong
PLEASE HELP :(

[
{book1={title:"Eat Pray Love", price:"$3.99"},
{book2={title:"DaVinci Code", price:"$7.99"}}
]
is not valid javascript. If you are trying to define an object literal you'll need to adjust your syntax a bit:
$scope.allbooks = [
{title:"Eat Pray Love", price:"$3.99"},
{title:"DaVinci Code", price:"$7.99"}
]
Now you can access each book:
$scope.allbooks[0]; // returns first book
$scope.allbooks[1]; // returns second book

in controller:
$scope.allbooks=[
{book1:{title:"Eat Pray Love", price:"$3.99"}},
{book2:{title:"DaVinci Code", price:"$7.99"}}
];
$scope.choice = {}; //a variable to store your choice
$scope.pick=function(name){
$scope.choice = $scope.allbooks[name];
}
in html template
<ion-item ng-click="pick('book1')"> <!-- pass book1 as string -->
{{choice.title}}
angular.module("app", [])
.controller("main", function($scope) {
$scope.allbooks = {
book1: {
title: "Eat Pray Love",
price: "$3.99"
},
book2: {
title: "DaVinci Code",
price: "$7.99"
}
};
$scope.choice = {}; //a variable to store your choice
$scope.pick = function(name) {
$scope.choice = $scope.allbooks[name];
}
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app" ng-controller="main">
<button ng-click="pick('book1')">Test</button>
<!-- pass book1 as string -->
{{choice.title}}
</div>

How to load template from dropdown menu Angular

I am fairly new to angular and am working with a client that wants a dropdown allowing users to select their neighborhood which is then saved in a cookie to load upon return. I am able to save cookie but am having trouble getting dropdown selected neighborhood to load proper template.
Here is the html:
<select id="mNeighborhood" ng-model="mNeighborhood" ng-options="neighborhood.id as neighborhood.name for neighborhood in neighborhoods" ng-change="saveCookie()"></select>
And then, I have added the following in html:
<div ng-view=""></div>
Here is the app.js code:
var app = angular.module('uSarasota', ['ngCookies', 'ngRoute']);
app.config(function ($routeProvider) {
$routeProvider
.when('/', {
template: '<div><h1 style="margin: 200px;">This is our main page</h1></div>'
})
.when('/downtown', {
templateUrl: "templates/downtown.html"
})
.otherwise({
template: '<div><h1 style="margin: 200px;""><strong>NOTHING TO SEE HERE</strong></h1></div>'
})
});
//Select Neighborhood
app.controller('myNeighborhood', ['$scope', '$cookies', function($scope, $cookies) {
$scope.neighborhoods = [{
name: "My Neighborhood",
id: 0
}, {
name: "All of Sarasota",
id: 1
}, {
name: "Downtown",
url: "/downtown",
id: 2,
}, {
name: "North Sarasota",
id: 3
}, {
name: "Lakewood Ranch",
id: 4
}, {
name: "Longboat Key",
id: 5
}, {
name: "St. Armands Circle",
id: 6
}, {
name: "Southside Village",
id: 7
}, {
name: "Siesta Key",
id: 8
}, {
name: "Gulf Gate",
id: 9
}];
//Set Cookie so when user returns to site, it will be on their neighborhood
$scope.mNeighborhood = parseInt($cookies.get('sNeighborhood')) || 0;
$scope.saveCookie = function() {
$cookies.put('sNeighborhood', $scope.mNeighborhood);
};
}]);
This all works fine to save and load user selection, but am having trouble finding solution to get template based on selection. So, should I add url to the array for each neighborhood and if so, how do I get the link?

Basically you need to change the URL programatically on selection of dropdown. For achieving this thing you need to first change you ng-options to return object on selection. And then using that object get url property from it to load particular template.
Markup
<select id="mNeighborhood"
ng-model="mNeighborhood"
ng-options="neighborhood.name for neighborhood in neighborhoods"
ng-change="saveCookie()">
</select>
Code
$scope.saveCookie = function() {
var mNeighborhood = $scope.mNeighborhood;
$cookies.put('sNeighborhood', mNeighborhood.id);
//do add $location dependency in controller function before using it.
$location.path(mNeighborhood.url);
};
Update
On initial Load the value should be set as object as per new implementation.
$scope.mNeighborhood = {}; //at the starting of controller
//the other code as is
//below code will get the object from the neighborhoods array.
$scope.mNeighborhood = $filter('filter')($scope.neighborhoods, parseInt($cookies.get('sNeighborhood')) || 0, true)[0];
$scope.saveCookie = function() {
var mNeighborhood = $scope.mNeighborhood;
$cookies.put('sNeighborhood', mNeighborhood.id);
//do add $location dependency in controller function before using it.
$location.path(mNeighborhood.url);
};

Add item to array Angular

I have a table with these fields: product, lot, input1, input2. You can clone a line, and you can add a new line.
What I want to do is that for each row you can add a new Lot created by a "number" and by "id" that user write in the input field under the Select lot. And I wanted that the script add the new Lot in the json data and the lot 's option list.
This is the function for add that I tried to do:
$scope.addLot = function() {
var inWhichProduct = row.selectedProduct;
var newArray = {
"number": row.newLot.value,
"id": row.newLot.id
};
for (var i = 0; i < $scope.items.length; i++) {
if ($scope.items[i].selectedProduct === inWhichProduct) {
$scope.items[i].selectedLot.push(newArray);
}
}
};
-->> THIS <<-- is the full code.
Can you help me?

I think your question is a little too broad to answer on Stack Overflow, but here's an attempt:
<div ng-app="myApp" ng-controller="myCtrl">
<table>
<tr ng-repeat="lot in lots">
<td>{{ lot.id }}</td>
<td>{{ lot.name }}</td>
</tr>
</table>
<p>name:</p> <input type="text" ng-model="inputName">
<p>id:</p> <input type="text" ng-model="inputId">
<button ng-click="addLotButton(inputId, inputName)">Add</button>
</div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.5.0-beta.2/angular.min.js"></script>
<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.lots = [{
name: "test",
id: 1
},
{
name: "test2",
id: 2
}
];
$scope.addLot = function(lotId, lotName) {
var newLotObject = {
name: lotName,
id: lotId
};
$scope.lots.push(newLotObject);
};
$scope.addLotButton = function(id, name) {
$scope.addLot(id, name);
};
$scope.addLot(3, "Another test");
});
</script>
Basically this code just takes some input and adds an object to the scope for that input. The table is created using an ng-repeat of this data. It's not great code at all but it's just a quick example.

The push method adds newArray to selectedLot array. It's not working on the JSON data but on arrays. If you want to have the JSON, you can give a try to :
var myJsonString = JSON.stringify(yourArray);
It will create a JSON string based on the parameter
Maybe you should try to structure your data to make lots as properties of products.
{
products: [
{id: 1, lots: [{id:1}, {id:2}]},
{id: 2, lots: [{id:1}, {id:2}]}
]
}
To add a lot to a product :
product = products[0];
product.lots.push(newArray);

Change the fallowing:
html:
<button ng-click="addLot(row.selectedProduct.id,row.newLot.value,row.newLot.id)">Add</button>
js:
$scope.addLot = function(id,val,lotId) {
// console.log(id);
var inWhichProduct = id;
var newArray = { "value": val, "id": lotId };
//console.log($scope.items)
angular.forEach($scope.items,function(v,i){
if($scope.items[i].id == id )
{
$scope.items[i].lots.push(newArray);
console.log($scope.items[i].lots);
}
});
};

Filtering an ng-repeat based on multiple values in angular

This is difficult to phrase but:
I have 1 collection called users.
Every user has 3 properies: id, name, skill.
{
_id: 1,
name: 'frank young',
skill: 'java'
},
I have 1 form collects search results upon pressing enter.
<form ng-submit="pushToNewArry(searchTerm)">
<input type="text" ng-model="searchTerm" />
<input type="submit">
</form>
this is not the best way to do this
$scope.newUsers = [];
$scope.pushToNewArry = function(msg) {
$scope.trackedUsers.push(msg);
$scope.searchTerm = '';
};
Question:
How do I create a filter that will run over multiple search terms and create a list proper matches based on the users collections vs inputed values.
<ol ng-repeat = "user in users | filter: trackedUsers">
<li class="names"><span>{{$index}}. </span>{{user.name}}</li>
<li class="skills">{{user.skill}}</li>
</ol>
Upon submission, the user input will be saved and create a new array of users based on inputed values of search. therefore, multiple matching values.

not excatly the same as example above because I keep playing with it.

}, 0) > 0;
}
};
$scope.saveSearchTerm = function () {
$scope.listSearchTerms.push($scope.searchTerm);
$scope.searchTerm = "";
