Push one array values to another array using anjularjs

Question

I have 2 arrays named as taxes and subitems

$scope.taxes=[];

$scope.subitems=[];

how can we save taxes values to subitems?

In taxes array i have field names id and value

in the same way at subitems we have aid and text

if i done any modification on taxes that can be goes to subitems

here i have declared diffterent field names

i didn't get how to solve this issue

please could any body help me

i am searching for this solution since 2 months onwards 

 

refer this plunker:http://next.plnkr.co/edit/SKrGEOvIlWSCzaZd?open=lib%2Fscript.js&deferRun=1&preview 

 

If any one know i can share databases aslo 

 

I have 2 databases

 

database1

id         value

 

1          111

 

2          bbb

 

after we click click button the above grid view can be populating from database

 

for each row same grid view can be displayed

 

if i done any modifications that can belong that particular row only

 (here i am going to change bbb....>aaa)

 

database 2

 

aid     text

1          111

2           aaa 

 

so finally we are fetching values from one database 

and we are going to save into another database
