attach events for the elements which are in a div

attach events for the elements which are in a div

Hi Team,

I have tow div's say divA and divB. Both are overlapping 

divB is having higher z-index -11
divA is having z-index - 10

Now dynamically i add div elements to and thosed divs have class attribute has "subdivs" divA

and i want to add double click event for the child elements added to divA

i tried below ways but did not work out

$("#iddivA').delegate("dblclick",".subdivs",function(){console.log("hellow")})

$("#iddivA').on("dblclick",".subdivs",function(){console.log("hellow")})

but none of the divs events are triggering ?

is it because of z-index ??/

 is there any way pls help me out

thanks & regards
