WPF MVVM Binding x:Name 不是触发方法

Question

I'm new to WPF, started trying to learn it on Wednesday. I have started looking into Caliburn.Micro and MVVM and I have used MaterialDesignInXAML Nuget package for a material design in the app. From this I have created a basic application that I want to use. This app has drawer menu that slides out from the side. On this menu, I have a number of buttons. I want to be able to click these buttons and have my ContentControl Update with the relevant UserControl Views I have created. I have LoadHome() in the public ShellViewModel(){LoadHome();} Method and this loads when i start the app, however clicking the buttons in the menu does not update the contentcontrol nor does it trigger any break points, even thought it is using the same x:Name="" syntax the others use. If i take the buttons off the menu and place them after, The button click works as expected and updates the contentcontrol.

My Code

ShellView.XAML

 <DockPanel>
                           <Button x:Name="LoadHome"
                            Margin="4" HorizontalAlignment="Center"
                            Style="{DynamicResource MaterialDesignFlatButton}">
                        HOME
                    </Button>
                    <Button x:Name="LoadBlobPurge"
                            Margin="4" HorizontalAlignment="Center"
                            Style="{DynamicResource MaterialDesignFlatButton}"
                            materialDesign:RippleAssist.Feedback="{Binding RelativeSource={RelativeSource 
    Self}, Path=Foreground, Converter={StaticResource BrushRoundConverter}}"
    >
                        BLOB PURGE TOOL
                    </Button>
                    <Button Command="{x:Static materialDesign:DrawerHost.CloseDrawerCommand}"
                            Margin="4" HorizontalAlignment="Center"
                            Style="{DynamicResource MaterialDesignFlatButton}">
                        APP 2
                    </Button>
                    <Button Command="{x:Static materialDesign:DrawerHost.CloseDrawerCommand}"
                            Margin="4" HorizontalAlignment="Center"
                            Style="{DynamicResource MaterialDesignFlatButton}">
                        APP 3
                    </Button>
                    <Button Command="{x:Static materialDesign:DrawerHost.CloseDrawerCommand}"
                            Margin="4" HorizontalAlignment="Center"
                            Style="{DynamicResource MaterialDesignFlatButton}">
                        CLOSE
                    </Button>
                    <Button x:Name="LoadHowTo"
                            Margin="4" HorizontalAlignment="Center"
                            Style="{DynamicResource MaterialDesignFlatButton}">
                        <materialDesign:PackIcon Kind="About" />
                    </Button>
                    
**ShellViewModel.cs**

        public class ShellViewModel : Conductor<object>
    {
        public ShellViewModel()
        {
            LoadHome();
        }

        public void LoadHome()
        {
            ActivateItem(new HomeViewModel());
        }

        public void LoadBlobPurge()
        {
            ActivateItem(new BlobPurgeViewModel());
        }

        public void LoadHowTo()
        {
            ActivateItem(new HowToViewModel());
        }

        public void LoadApp2()
        {
            
        }

        public void LoadApp3()
        {
            
        }

    }

As you are using Caliburn.Micro you can try to use the following syntax on the button. x:Name binding also failed me when using MaterialDesignInXAML.

<Button cal:Message.Attach="[Event Click] = [Action LoadBlobPurge()]"
                    Margin="4" HorizontalAlignment="Center"
                        Style="{DynamicResource MaterialDesignFlatButton}"
                        materialDesign:RippleAssist.Feedback="{Binding RelativeSource= 
   {RelativeSource Self}, Path=Foreground, Converter={StaticResource BrushRoundConverter}}">                       
LOAD BLOB PURGE </Button>
