angular $broadcast event is not firing?

I want to send data from parent to child controller but its not firing event from parent controller its been hours i am scratching my head find the problem but i failed so decided to ask help on stackoverflow, Any idea what is wrong in below code ?
ParentCtrl.js
angular.module('angularModelerApp')
.controller('ModelerCtrl', ['$scope', '$state','$log', 'toastr', 'FileSaver', 'Blob', '$uibModal', '$rootScope', '$timeout', function($scope, $state, $log, toastr, FileSaver, Blob, $uibModal, $rootScope, $timeout) {
$scope.deleteXml = function(id, toast) {
var id = $scope.diagramObj._id;
$scope.modalInstance = $uibModal.open({
templateUrl: 'app/modeler/modelerDialog/modelerDialog.html',
controller: 'ModelerDialogCtrl'
});
$timeout(function() {
$rootScope.$broadcast('delete-diagram', {
id: id
});
});
}
});
childCtrl.js
angular.module('angularModelerApp')
.controller('ModelerDialogCtrl', function ($scope, $uibModalInstance,$log,diagramService,$rootScope) {
$scope.cancel = function() {
$uibModalInstance.dismiss('cancel');
};
$scope.$on('delete-diagram',function(e,data){
console.log('in $on',data);
});

Why dont you pass the id when you open the modal such as:
$scope.modalInstance = $uibModal.open({
templateUrl: 'app/modeler/modelerDialog/modelerDialog.html',
controller: 'ModelerDialogCtrl',
resolve: {
item: function() {
return $scope.diagramObj._id
}
}
});
Fetch it in the child component in this way:
angular.module('angularModelerApp')
.controller('ModelerDialogCtrl', function ($scope, $uibModalInstance,$log,diagramService,$rootScope) {
$scope.cancel = function() {
$uibModalInstance.dismiss('cancel');
};
$scope.$on('delete-diagram',function(e,data){
console.log('in $on',data);
});
$uibModalInstance.result.then(function (data) {
console.log(data);
})
}

$location.path() not working in AngularJS

I have been trying to redirect my application to the following link using
$location.path('/enterprise/update/' + enterprise.id);
The current url when I click the button is http://localhost:8080/#/enterprise/view
and I would like it to be changed to http://localhost:8080/#/enterprise/update/0
(The 0 here represents the id)
The edit function is the one which is called when I click on the button to redirect.
Relevant code:
EnterpriseCtrl.js
app.controller('EnterpriseCtrl', ['$scope', 'Enterprise', '$location','$http','$route','$routeParams','$resource', function($scope, Enterprise, $http, $route, $location, $rootScope) {
$scope.enterprises = Enterprise.list({}, function (response) {
return response;
});
$scope.add = function(){
Enterprise.save($scope.enterprise,function (){});
$scope.enterprise = null;
};
$scope.delete = function(enterprise, index){
alert("Do you really want to delete an Enterprise at index " + (index+1) + "?");
//book.$remove();
Enterprise.remove(enterprise);
$scope.enterprises.splice(index, 1);
};
$scope.edit = function(enterprise){
console.log(enterprise.id);
console.log(location);
console.log($location);
$location.path('/enterprise/update/' + enterprise.id);
};
// $scope.enterprise = Enterprise.get({id: $route.current.params.id});
$scope.update = function(){
Enterprise.update($route.current.params.id);
$location.path($rootScope.history.view);
};
}]);
app.js
var app = angular.module('mpsApp', ['ngRoute','ngResource']);
app.config(['$routeProvider','$locationProvider',
function ($routeProvider,$locationProvider) {
$routeProvider.
when('/', {
templateUrl: 'home.html'
}).
when('/enterprise/view', {
controller: 'EnterpriseCtrl',
templateUrl: 'showEnterprise.html'
}).
when('/enterprise/add', {
controller: 'EnterpriseCtrl',
templateUrl: 'addEnterprise.html'
}).
when('/enterprise/update/:id', {
controller: 'EnterpriseCtrl',
templateUrl: 'updateEnterprise.html'
}).
otherwise({
redirectTo: '/'
});
}
]);
The error that I get is
TypeError: $location.path is not a function
at Scope.$scope.edit (EnterpriseCtrl.js:29)
at $parseFunctionCall (angular.js:12330)
at callback (angular.js:22940)
at Scope.$eval (angular.js:14381)
at Scope.$apply (angular.js:14480)
at HTMLButtonElement.<anonymous> (angular.js:22945)
at HTMLButtonElement.eventHandler (angular.js:3009)

Your dependency injection array/parameters are out of order. Should be:
[ '$scope', 'Enterprise', '$location', '$http', '$route', '$routeParams', '$resource',
function($scope, Enterprise, $location, $http, $route, $routeParams, $resource) {
Note, how each single array element service corresponds to the parameters in the function.

Angular directive controller: Argument is not a function, got undefined

I have created a directive inside my controller, which i want to include another controller to the directive. The error i get back is Error: [ng:areq] Argument 'js/controllers/testview/DocumentController.js' is not a function, got undefined
TestviewController
app.controller('TestviewController', ['$http', '$scope', '$sessionStorage', '$state', '$log', 'Session', 'api', function ($http, $scope, $sessionStorage, $state, $log, Session, api) {
var module_id = $state.params.id;
$http.get(api.getUrl('componentsByModule', module_id))
.success(function (response) {
$scope.components = response;
});
}]);
app.directive('viewDoc', function () {
return {
templateUrl: "tpl/directives/testview/document.html",
controller: "js/controllers/testview/DocumentController.js",
resolve: { components: function() { return $scope.components }}
};
});
DocumentController
app.controller('DocumentController', ['$http', '$scope', '$sessionStorage', '$state', '$log', 'Session', 'api', 'components', function ($http, $scope, $sessionStorage, $state, $log, Session, api, components) {
$scope.components = components;
}]);
I'm pretty new with directices, but does anyone have any idea what I'm doing wrong?

Inside the directive definition object, the controller property expects a string with the function name, or the function itself (not the path to script file).
app.directive('viewDoc', function () {
return {
...
controller: "DocumentController",
};
});

You want to call the controller by name, not by file name:
controller: "js/controllers/testview/DocumentController.js"
should be
controller: "DocumentController"

There is no option to put controller by its URL in the directive definition. However if you define your controller in DOM template you could use controller: 'myController as myCtrl' in directive definition

are you sure you need a directive controller? i think what you are trying to achieve is link function.
you can use directive link functions like controllers.
.directive('myDialog', function() {
return {
restrict: 'E',
transclude: true,
scope: {},
templateUrl: 'my-dialog.html',
link: function (scope, element) {
scope.name = 'Jeff';
}
};
});

Angular: Passing params from $routeProvider to controller

I have multiple routes that invoke the same Controller and I would like to pass different variables to it.
// Example
$routeProvider.
when('/a', {
templateUrl: 'test.html',
controller: 'MyController' // should get passed 'exampleA'
}).
when('/b', {
templateUrl: 'test.html',
controller: 'MyController' // should get passed 'exampleB'
});
I know that I could use the "resolve" object:
$routeProvider.
when('/a', {
templateUrl: 'test.html',
controller: 'MyController',
resolve: {test: function() { return true; }}
});
To pass a value as a dependency:
app.controller('MyController', ['$scope', 'test', function ($scope, test) {
console.log(test); // true
}
My problem with that approach is that my app crashes if the resolve object is missing on other routes and I would like to pass optional params.
Is there any way to pass specific params to the Controller (from the route provider)?
Thank you

Routing:
$routeProvider.
when('/a', {
templateUrl: 'test.html',
controller: 'MyController',
paramExample: 'exampleA'
}).
when('/b', {
templateUrl: 'test.html',
controller: 'MyController',
paramExample: 'exampleB'
});
Access: inject $route in your controller then use this
app.controller('MyController', ['$scope', '$route', function ($scope, $route) {
var paramValue = $route.current.$$route.paramExample;
console.log(paramValue);
}

You can use resolve and $route.currrent.params.test to pass the parameter like this:
$routeProvider
.when('/a', {
templateUrl: 'view.html',
controller: 'MainCtrl',
resolve: {
test: function ($route) { $route.current.params.test = true; }
}
})
.when('/b', {
templateUrl: 'view.html',
controller: 'MainCtrl',
resolve: {
test: function ($route) { $route.current.params.test = false; }
}
})
Then in your controller you can access it from the $routeParams:
app.controller('MainCtrl', function($scope, $routeParams) {
$scope.test = $routeParams.test;
})

The most natural way to do this is doing what you would normally do when you want to load a page with parameters: use query parameters: http://yoururl.com?param1=value&param2=value
ngRoute comes with the service $routeParams which you can inject in your controller. Now you can simply retrieve the values like this $routeParams.param1.
Another way to do this is to retrieve the path with $location.path and set the variable there.

using $routeParams
in Main js file
routeApp.config(function($routeProvider) {
$routeProvider
.when('/home', {
templateUrl: '../sites/./home.html',
controller: 'StudentController'
})
.when('/viewStudents/:param1/:param2', {
templateUrl: '../sites/./viewStudents.html',
controller: 'StudentController'
})
.otherwise({
redirectTo: '/'
});
});
routeApp.controller('StudentController',['$filter','$routeParams', '$location',function($filter,$routeParams,$location){
var StudentCtrl = this;
StudentCtrl.param1 = $routeParams.param1;
StudentCtrl.param2 = $routeParams.param2;
}]);
calling from Home.html
<div class="container">
<h2> Welcome </h2>
Students
</div>

$routeParams Empty on $locationChangeSuccess

I configure my app in the following run block. Basically I want to preform an action that requires me to know the $routeParams every $locationChangeSuccess.
However $routeParams is empty at this point! Are there any work rounds? What's going on?
app.run(['$routeParams', function ($routeParams) {
$rootScope.$on("$locationChangeSuccess", function () {
console.log($routeParams);
});
}]);
UPDATE
function configureApp(app, user) {
app.config(['$routeProvider', function ($routeProvider) {
$routeProvider.
when('/rentroll', {
templateUrl: 'rent-roll/rent-roll.html',
controller: 'pwRentRollCtrl'
}).
when('/bill', {
templateUrl: 'bill/bill/bill.html',
controller: 'pwBillCtrl'
}).
when('/fileroom', {
templateUrl: 'file-room/file-room/file-room.html',
controller: 'pwFileRoomCtrl'
}).
when('/estate-creator', {
templateUrl: 'estate/creator.html'
}).
when('/estate-manager', {
templateUrl: 'estate/manager.html',
controller: 'pwEstateManagerCtrl'
}).
when('/welcomepage', {
templateURL: 'welcome-page/welcome-page.html',
controller: 'welcomePageCtrl'
}).
otherwise({
redirectTo: '/welcomepage'
});
}]);
app.run(['$rootScope', '$routeParams', 'pwCurrentEstate','pwToolbar', function ($rootScope, $routeParams, pwCurrentEstate, pwToolbar) {
$rootScope.user = user;
$rootScope.$on("$locationChangeSuccess", function () {
pwToolbar.reset();
console.log($routeParams);
});
}]);
}
Accessing URL:
http://localhost:8080/landlord/#/rentroll?landlord-account-id=ahlwcm9wZXJ0eS1tYW5hZ2VtZW50LXN1aXRlchwLEg9MYW5kbG9yZEFjY291bnQYgICAgICAgAoM&billing-month=2014-06

this worked for me, inside your run callback:
.run(function($rootScope, $routeParams, $location) {
$rootScope.$on("$locationChangeSuccess", function() {
var params = $location.search();
console.log(params);
console.log('landlord-account-id:', params['landlord-account-id']);
console.log('billing-month', params['billing-month']);
});
})

By accessing /rentroll you will get empty $routeParams because your $routeProvider
configuration for that path is not expecting any variable on URL.
$routeParams is used for getting variable value of your URL. For example :
$routeProvider
.when('/rentroll/:variable', {...});
and access it on /rentroll/something will give you $routeParams as below :
$routeParams.variable == 'something';

https://docs.angularjs.org/api/ngRoute/service/$routeParams
Explains a bit about when the $routeParams are available and why.
To solution here might be to use $route.current.params
