Rendering columns cannot find function in page content

I see that Issue #2014 is similar to what I am facing. I am testing the SQL CRUD dashboard example and using pages files for various pages. I keep getting the Invoke cannot find the term New-UserEditButton and the function is in the same Page file as the UDTable that is rendering the column, so not sure what was happening until I saw the example for Issue #2014.
I have put together code that I can reproduce the issues as it turns out the render cannot find variables or function within the the pages content section.

New-UDDashboard -Title "Test" -Pages @(
    New-UDPage -Name "Page 1" -Content {
        $MyVar = 'Testing'
        function New-ButtomCustom {
            New-UDButton -Text "Click for Dessert!" -OnClick {
                Show-UDToast -Message $EventData.Dessert
            }
        }
        $Data = @(
            @{Dessert = 'Frozen yoghurt'; Calories = 1; Fat = 6.0; Carbs = 24; Protein = 4.0}
            @{Dessert = 'Ice cream sandwich'; Calories = 159; Fat = 6.0; Carbs = 24; Protein = 4.0}
            @{Dessert = 'Eclair'; Calories = 159; Fat = 6.0; Carbs = 24; Protein = 4.0}
            @{Dessert = 'Cupcake'; Calories = 159; Fat = 6.0; Carbs = 24; Protein = 4.0}
            @{Dessert = 'Gingerbread'; Calories = 200; Fat = 6.0; Carbs = 24; Protein = 4.0}
        ) 
        
        $Columns = @(
            New-UDTableColumn -Property Dessert -Title Dessert -Render { 
                Show-UDToast -Message $MyVar
                New-ButtomCustom
            }
            New-UDTableColumn -Property Calories -Title Calories 
            New-UDTableColumn -Property Fat -Title Fat 
            New-UDTableColumn -Property Carbs -Title Carbs 
            New-UDTableColumn -Property Protein -Title Protein 
        )
        New-UDTable -Columns $Columns -LoadData {
            $TotalCount = $Data.Count
            $Data | Out-UDTableData -Page $EventData.Page -TotalCount $TotalCount -Properties $EventData.Properties
        } -Sort -Export
    
    }
)

This code only works when the $MyVar and New-ButtomCustom function are above the Dashboard code, so is this a bug? Should I be adding all the functions and variables to the Dashboard code and not in the pages content section? Please advise

Functions will not work like this at the moment. I would recommend either placing them at the root (dashboard) scope or within a module to ensure they are available within the render methods.

In terms of variables, I would have expected this to work. A work around would be to use a session variable.

New-UDDashboard -Title "Test" -Pages @(
    New-UDPage -Name "Page 1" -Content {
        $Session:MyVar = 'Testing'
        function New-ButtomCustom {
            New-UDButton -Text "Click for Dessert!" -OnClick {
                Show-UDToast -Message $EventData.Dessert
            }
        }
        $Data = @(
            @{Dessert = 'Frozen yoghurt'; Calories = 1; Fat = 6.0; Carbs = 24; Protein = 4.0}
            @{Dessert = 'Ice cream sandwich'; Calories = 159; Fat = 6.0; Carbs = 24; Protein = 4.0}
            @{Dessert = 'Eclair'; Calories = 159; Fat = 6.0; Carbs = 24; Protein = 4.0}
            @{Dessert = 'Cupcake'; Calories = 159; Fat = 6.0; Carbs = 24; Protein = 4.0}
            @{Dessert = 'Gingerbread'; Calories = 200; Fat = 6.0; Carbs = 24; Protein = 4.0}
        ) 
        
        $Columns = @(
            New-UDTableColumn -Property Dessert -Title Dessert -Render { 
                Show-UDToast -Message $Session:MyVar
                New-ButtomCustom
            }
            New-UDTableColumn -Property Calories -Title Calories 
            New-UDTableColumn -Property Fat -Title Fat 
            New-UDTableColumn -Property Carbs -Title Carbs 
            New-UDTableColumn -Property Protein -Title Protein 
        )
        New-UDTable -Columns $Columns -LoadData {
            $TotalCount = $Data.Count
            $Data | Out-UDTableData -Page $EventData.Page -TotalCount $TotalCount -Properties $EventData.Properties
        } -Sort -Export
    
    }
