Ng-submit Not Triggering In Angularjs

I got no error in my console, but my ng-submit is just not triggering. I debug by putting something in my controller, it did trigger, means it's not the problem of my controller no

Solution 1:

try this:

signup.js

(function () {
    /* jshint validthis: true */
    'use strict';

    angular
        .module('MyApp')
        .controller('Signup', Signup);

    Signup.$inject = ['$scope', '$rootScope', '$location', '$window', '$auth'];

    function Signup($scope, $rootScope, $location, $window, $auth) {
        var vm = this;
        vm.signup = signup;
        vm.user = ...;

        function signup() {
            console.log('trigger');
        }
    }
})();

signup.html

<section id="signup-view" data-ng-controller="Signup as vm">
    <form>
        <div class="form-group">
            <label for="name">First Name</label>
            <input required type="text" name="fname" id="fname" placeholder="First Name" class="form-control" ng-model="vm.user.fname" autofocus>
        </div>
        <button class="btn btn-success" data-ng-click="vm.signup()">Sign up</button>
    </form>
</section>

As a side note, you missed two ';' in your code. I suggest you regularly test your JS code with a tool like JSHint.
