Bind variables to combobox and textbox in Powershell - wpf

Question

I'm coming with more problems to you.
I've built a simple GUI to create a printer or change the driver on a print server. However, when I click the button RUN, it does not make anything just only pops up the message that the operation was successful. May somebody help me checking the code and tell me what I am doing wrong?

Also I would like to link the model selection to another variable called 'model' that will use a shortcut of the model to deploy some specific settings and once the Operation success mesasge' pops up and you press OK, all comboboxes and texboxes reset to blank.
FYI: PortCreation, PrinterCreation, ChangeDriver and ApplyConfigLexmark are functions that execute code in Powershell so I am not putting the whole code. Variables that I am using are below:
$maker # choose the brand of the physical device
$model # short name of the device model
$modelfull # Full device model
$tray # number of the trays the device has
$driver # Driver name
$PQ # print queue name
$server # hostname of the server
$hostname # hostname of the printer
$location # location of the device

Answer 1

I tested your code and changed this line to show the maker and it works. Why do you say the variable is not binding?
[System.Windows.MessageBox]::Show('Operation completed!' + $maker)
Also Checked should be IsChecked
if ($RadioCreate.IsChecked -eq $true){
