how to clear data in modal view of ionic - ionic-framework

Question

I have tried a lot of things to clear the input fields in ionic modal. It has already been more than two days I have been searching for the solution. Can anyone provide me the solution? I have only included the necessary parts.
controller.js
.controller('ClientCtrl', ['$scope', '$ionicModal', function($scope, $ionicModal) {
//I have retrieved data form local storage
//$scope.clients contains the data
//client add modal
$ionicModal.fromTemplateUrl('templates/clientAdd.html', {
scope: $scope
}).then(function(modal) {
$scope.clientAdd = modal;
});
// Triggered in the client add modal to close it
$scope.closeClientAddForm = function() {
$scope.clientAdd.hide();
};
// Open the client add modal
$scope.clientAddForm = function() {
$scope.clientAdd.show();
};
}])
.controller('ClientAddCtrl', ['$scope', '$state', function($scope, $state) {
//$scope.client = null;
$scope.client = {};
$scope.addClientData = function(clientData) {
$scope.clientinfo = clientData;
//operation to store data
/* $scope.clearForm = function() {
var client = {
companyName: "",
address: "",
contactName: "",
contactEmail: "",
contactPhone: "",
shippingName: "",
shippingAddress: ""
}
$scope.clientAddForm.$setPristine();
$scope.client = angular.copy(client);
}*/
$scope.closeClientAddForm();
}
}])
