how make bootstrap 4 modal work when click on modal button popup is shown

It looks like you’re trying to open the bootstrap modal, passing an id to it. Am I reading your intent correctly?

If so, that’s not how the modals work in bootstrap. The data-target attribute points to an id on the modal. So unless you have a modal for each id (and you shouldn’t), that’s not what you want. Look at the Varying modal content in the modal documentation. That’s the approach you want to use.
