My angular form validation doesn't work

Question

I use bootstrap with angular, and I disabled bootstrap's validation, angular still doesn't work. It seems that I already set everything.

My code likes below, every input's validation didn't.

<form novalidate name="new_people" ng-if="is_editting_newpeople" class="form-horizontal" role="form" ng-submit="save_new_people()">    
    <div class="input-group">
        <div class="input-group-addon">True Name</div>
        <input class="form-control" name="realname" type="text" ng-model="editting_people.realname" autofocus required>
    </div>

    <div class="input-group">
        <div class="input-group-addon">Nickname</div>
        <input type="text" name="nickname" class="form-control" id="nickname" ng-model="editting_people.nickname" required>
    </div>
    <div class="input-group">
        <div class="input-group-addon">Mobilenumber</div>
        <input type="text" class="form-control" id="mobile" name="mobilenumber" ng-model="editting_people.mobilenumber" required ng-minlength=11>
    </div>
    <div class="input-group">
        <div class="input-group-btn">
            <button type="button" class="btn btn-default
                        dropdown-toggle" data-toggle="dropdown">{{ editting_people.idclass.name }}
                      <span class="caret"></span>
                    </button>
            <ul class="dropdown-menu">
                <li ng-repeat="id_class in IDCLASSES">
                    <a ng-click="set_id_class(id_class)">{{ id_class.name }}</a>
                </li>
            </ul>
        </div>
        <!-- /btn-group -->
        <input type="text" class="form-control" ng-model="editting_people.idnumber" required name="idnumber">
    </div>
    <!-- /input-group -->
    <br>
    <input class="btn btn-primary" type="submit" value="Submit" />
    <input class="btn btn-default" value="取消" type="button" ng-click="cancel_new_people()" />
</form>

What do you mean by input doesn't work? Post your code of related controller please, because it is not clear what validation are you doing. If you have novalidate you should organize validation in your angular controller or HTML, eg:

<div ng-show="editting_people.realname.length<4">
 Any error message here.
</div>
