How to debug Javascript (Custom) in CRM 2015 using Browser

Hi there,

I have tried Debugging using IE 11 Developer Tools as well as Chrome. I can see my Javascript Code only under Dynamic Scripts and when I open it and add a breakpoint it is never reached. I have googled a lot but only found Infos related to CRM 2011 which are not working for CRM 2015 and new browser versions.

I have also tried adding following statment in the initialize code: Xrm.Utility.alertDialog("Inside alert statement"); 

it just Displays message box but donot break at that Point.

could anybody please tell me how to debug Javascript custom  in CRM 2015 using Browser? Thanks in advance!
