How to call javascript function from js.erb

[aswani521]

I am new to ruby this might be something which is obvious.

I am trying to call my addmarker() function which can add a marker to my  Google map.

In my js.erb i tried to include the function call within the <script> tags, but the function addmarker() is not being called. 

Has anyone faced a similar problem ? 

I am trying to avoid using a gem for my case.
