your input should look like this

<input type="text" id="u_id" placeholder="User ID" ng-model="Nuser.userID" name="u_id" value="" maxlength="20" minlength="4" required/>

and you can show the alert like this

<div ng-show="userLogin.$submitted && userLogin.u_id.$invalid">
                    User Id is required.
                </div>

Bootstrap form with angularJS validation:

           <div class="form-group">

              <label class="col-sm-2 control-label" for="contactEmail">Email:</label>

              <div class="col-sm-4 col-sm-push-6">
                <div class="alert alert-danger" role="alert"
                      ng-show="contactForm.$submitted && contactForm.contactEmail.$invalid">
                  <strong><i class="fa fa-exclamation"></i> Error:&nbsp; </strong>
                  <span class="alert-inner">Email is too short.</span>
                </div>
              </div>

              <div class="col-sm-6 col-sm-pull-4">
                <input type="email" class="form-control" id="contactEmail" name="contactEmail"
                       placeholder="Ex. [email protected]"
                       maxlength="40" ng-model="contactMessage.email" required>
              </div>

            </div>
