You can put ng-submit like :

<form name="billdata" id="billdata" enctype="multipart/form-data" novalidate ng-submit="addClassData();">

or if you want to keep it button instead of submit buttton than below directive may help you.

angular.module('NgEnter', [])
    .directive('ngEnter', function() {
        return function(scope, element, attrs) {
            element.bind("keypress", function(e) {
                if(e.which === 13) {
                    scope.$apply(function(){
                        scope.$eval(attrs.ngEnter, {'e': e});
                    });
                    e.preventDefault();
                }
            });
        };
    });

and than call this directive to

<form name="billdata" id="billdata" enctype="multipart/form-data" novalidate ng-enter="addClassData();">
