Dataset and dynamic pages: how can i add edit bottom to allow members to edit.

Hi everyone!!
I’ve created my website with a page that has a form (consisted of costume inputs) and I linked the (inputs form) to a dataset to capture members’ answers and save them in a collection.
then I created a dynamic page which comes with repeater (automatically), I linked the repeater to a dataset so member X who submit the form can easily see it in the dynamic page, my question is how can I allow my members to access their submissions and let them edit it? could be possible with a bottom in each item in dynamic page and link it to what?

Hope its clear… waiting for your awesome answers:)
