Here are your little typos!

    private Boolean _textbox_enabled;
    public Boolean TextboxEnabled // here, underscore typo
    {
        get { return _textbox_enabled; }
        set
        {
            _textbox_enabled = value; // You miss this line, could be ok to do an equality check here to. :)
            OnPropertyChanged("TextboxEnabled"); // 
        }
    }

Another thing for your xaml to update the text to the vm/datacontext

Text="{Binding Path=Text, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" IsEnabled="{Binding TextBoxEnabled}"/>
