Using angular includes like mvc partials - angularjs

Question

Consider the following:
<script type="text/ng-template" id="myTemplateName">
{{item.SomeProperty}}
<script>
<div ng-repeat="container in List">
<div ng-repeat="item in container.Items">
<!-- CASE 1 -->
<div ng-include="'myTemplateName'"></div>
</div>
<!-- CASE 2 -->
<div ng-include="'myTemplateName'" />
</div>
The code above works in case1, but not in case2: case 1 will work because the template uses item, which is made available by the ng-repeat statement outside of the template, case 2 doesn't work because there is no item, instead i want it to use container.SomeProperty.
Maybe i am misusing angular includes, but i wanted to use them like partials in ASP.Net MVC. There, you can define a partial and you are able to pass in a model.
Is there any way in angular that allows me to set what item means inside the template?
Problem solved using Matt's answer:
module.controller("ItemController", ['$scope', function ($scope) {
$scope.templateitem = ($scope.$parent.item) ? $scope.$parent.item : $scope.$parent.$parent.container.Item;
}]);
Still, it feels kind of dirty: the controller needs to know how it can be used. It would be better if i could pass this to the controller from the outside.
A better approach:
I didnt really like the solution above, because the controller needs to know how it will be used, so i used a directive:
app.directive("opportunity", function () {
return {
restrict: "E",
templateUrl: "opportunityTemplate",
scope: { templateitem: "=model" }
};
});
In view:
<script type="text/ng-template" id="opportunityTemplate">
{{templateitem.SomeProperty}}
</script>
<opportunity model="container.Item"></opportunity>
<opportunity model="somethingElse.Item"></opportunity>
Now all i need to find out is how i can pass the templatename into the directive, and i can make a re-usable "partial" directive (please tell me if i am reinventing the wheel here?)

Answer 1

What you need to use is ng-controller, or some routing system like ui-router that connects partials to controllers through route definitions.
For the first example, when you add your partial, also specify a controller which takes care of dealing with the model:
HTML:
<div ng-controller="MyCtrl" ng-include="'myTemplateName'" />
<!-- inside the template -->
<div>{{item.somekey}}</div>
Controller:
angular.module('myapp.ctrl', [])
.controller('MyCtrl', ['$scope', function($scope){
$scope.item = { somekey: 'somevalue' };
}]);
In the second example, use a routing system like ui-router. An example of that can be seen here, where certain partials are attached to controllers and specific urls:
