one button is in heart of other button , if set a function to parent of button child button instead of do itself action do parent , 

--------------------------------------------
|   ----------                             |
|   | Child  |  Parent (class="btn")       |
|   ----------                             |
--------------------------------------------

if $(".btn").click(function () { return false; }); child return false too ! not navigate to it's own Link !

Added : it happen within any Clickable element like button in div , div in div , any Hierarchy structure, not just button in button , it`s just sample
