Then inserted that form into a Content Template (the template just acts as a container for the form, but it is needed with edit forms).
Then in the output of the View you insert a Fields and Text block and use the little orange Toolset Forms button to pull up a dialog which allows you to insert the edit form (you have to specify the template that contains the form). (Note, it is typically better to work in the HTML tab of the Fields and Text block so that you can see exactly what markup is being added.)
You've done all of that and the button doesn't appear at all?
