local build not working

this plugin is great everything is working just fine but i wanted one change. I am getting data from api side with that i am getting seperatly total row which we needed to show always on last row (after search/sort/filter). I made that change in library but after local build that plugin is not working.
I noticed when i get library from npm it's structure is different than my local build.

i am using below command

> ng build ng2-smart-table

from npm ->

and my local ->
