Buttons With Tbbuttongroup

Hello everyone,

I have the following code but the button is alway displaying in blue color( it seems to be the default)

It should be green as I am defining the class btn green.

Does anyone know what I doing wrong´?

Thanks


$this->widget("bootstrap.widgets.TbButtonGroup", array(

            "buttons"=>array(

                array(

                    "buttonType" =>"submit",

                    "type" =>"primary",

                    // // '', 'primary', 'info', 'success', 'warning', 'danger' or 'inverse'

                    "label" =>Yii::t("", "Save Button test"),

                    "htmlOptions" => array("class"=>"btn green")

                )

            )

        ) );

Look CSS inherit in firebag or use "type" =>"success", instead
