Editable Web Listbox Cell Project Needs Input

Hello,
I am looking at you example to edit a webtextfield. I am trying to incorporate into my app. What I got it so far where I click on the row I want (I am just changing Column 0), I am able to copy the contents of the current value but I can’t type or edit the value. for example, I click oh the last row below (REP. GUARDALODO DEL. RH) and I get to copy the value to the edit box but I can’t change it.

I did notice that there is an event “CustomCellAction” that I did not see in my current Weblistbox.

Maybe you have an updated example where the weblistbox has a few rows and I can edit the content of the first column on the row I clicked? That is what I am looking to do
