AngularJS – 使用ng-include时丢失范围

var mainModule = angular.module('lpConnect',[]).
    config(['$routeProvider',function ($routeProvider) {
    $routeProvider.
        when('/home',{template:'views/home.html',controller:HomeCtrl}).
        when('/admin',{template:'views/admin.html',controller:AdminCtrl}).
        otherwise({redirectTo:'/connect'});
}]);

首页html：

<div ng-include src="views.partial1"></div>

partial1 html：

<form ng-submit="addLine()">
    <input type="text" ng-model="lineText" size="30" placeholder="Type your message here">
</form>

首页控件：

function HomeCtrl($scope,$location,$window,$http,Common) {
    ...
    $scope.views = {
        partial1:"views/partial1.html"
    };

    $scope.addLine = function () {
        $scope.chat.addLine($scope.lineText);
        $scope.lines.push({text:$scope.lineText});
        $scope.lineText = "";
    };
...
}

在addLine函数$ scope.lineText是未定义的，这可以通过添加ng-controller =“HomeCtrl”到partial1.html来解决，但是它会导致控制器被调用两次，我在这里缺少什么？
