Does not saves from fields

[vasyl-dmytruk]

I have model class Gender:

class Gender extends \yii\db\ActiveRecord
{
     public function behaviors()
    {
        return [
            'ml' => [
                'class' => MultilingualBehavior::className(),
                'languages' => [
                    'uk' => 'Ukrainian',
                    'ru' => 'Russian',
                    'en' => 'English',
                ],
                //'languageField' => 'language',
                //'localizedPrefix' => '',
                //'requireTranslations' => false',
                //'dynamicLangClass' => true',
                'langClassName' => GenderLang::className(), // or namespace/for/a/class/PostLang
                'defaultLanguage' => 'uk',
                'langForeignKey' => 'gender_id',
                'tableName' => "{{%gender_lang}}",
                'attributes' => [
                    'name', 'short_name',
                ]
            ],
        ];
    }

    public static function find()
    {
        return new MultilingualQuery(get_called_class());
    }
}

and want to save it via ActiveForm fields in view like this:

<?php $form = ActiveForm::begin(); ?>

    <?php echo $form->errorSummary($model); ?>

    <?php echo $form->field($model, 'id')->textInput() ?>

    <div class="row">
        <div class="col-md-6">
            <?php echo $form->field($model, 'name')->textInput(['maxlength' => 255]) ?>
        </div>
        <div class="col-md-6">
            <?php echo $form->field($model, 'short_name')->textInput(['maxlength' => 255]) ?>
        </div>
    </div>

    <div class="row">
        <div class="col-md-6">
            <?php echo $form->field($model, 'name_ru')->textInput(['maxlength' => 255]) ?>
        </div>
        <div class="col-md-6">
            <?php echo $form->field($model, 'short_name_ru')->textInput(['maxlength' => 255]) ?>
        </div>
    </div>

    <div class="row">
        <div class="col-md-6">
            <?php echo $form->field($model, 'name_en')->textInput(['maxlength' => 255]) ?>
        </div>
        <div class="col-md-6">
            <?php echo $form->field($model, 'short_name_en')->textInput(['maxlength' => 255]) ?>
        </div>
    </div>



    <div class="form-group">
        <?php echo Html::submitButton($model->isNewRecord ? Yii::t('backend', 'Create') : Yii::t('backend', 'Update'), ['class' => $model->isNewRecord ? 'btn btn-success' : 'btn btn-primary']) ?>
    </div>

    <?php ActiveForm::end(); ?>

but it does not work, non of multilanguage fields does not save.
If I fill data directly in database, then it shows this fields.
P.S. Sorry for my English.

I have resolved this issue. I add rules to my model:

public function rules()
    {
        return [
            [['name', 'short_name', 'name_ru', 'short_name_ru', 'name_en', 'short_name_en'], 'safe'],

        ];
    }

@SnapGet You should use rules like this

public function rules()
    {
        return [
            [['name', 'short_name'], 'string', 'max' => 255] ,

        ];
    }
