Modal opens up only once on button click in R Datatable shiny app

[sten]

I have a table in which I am saving the bookmark URL. As of now when you click on the button it opens the modal. But as soon as you have the second record and click on that button it doesn't open up the modal. Also when the modal opens as of now it has a href. How can I clean it up and just show the URL?
