MVC w/ Razor View - Form POST

Hi All, I am trying to wrap my head around MVC in Razor pages, as I inherited some legacy stuff at work. I am trying to figure out why when I click my "submit" button on my Razor page, a blank page renders, and my breakpoint in my controller method for the post is never hit. What am I doing wrong?
