Syntax error using Javascript in Rails 4 -

for project in rails 4, working part of code in javascript having error in console. when working directly numbers error disappear. explain better code:

here javascript's code in index.html.erb

this controller (how receive data ajax):

the error happens when calling ajax when data refers to: eigen_eco4,autarkie_eco4 ans on, , console log points to: financecalc.

when changing these data directly numbers (23,34 each eigen_eco4,autarkie_eco4 etc) not appear.

does have idea of missing?
