I am working on project, from datatable i have button, when user
clicks on it, it will open popup and shows pdf, (which i am
rendering). Once user closed modal, next time if he opens button,
it will show previous data. its not refreshing.
I have tried $(this).removeData('bs.modal'); it doesn't worked
for me.
Here is my Modal code. Any idea how we can refresh only modal in
Javascript?
