Hello everyone.
First of all, English is not my native language, so there may be errors in the writing of this topic. Thank you
I have a query on a topic in meteor that I can not solve because I am still very new to this area.
I am creating a project that allows to search an author in google scholar through his ID and display the data through graphics in d3plus. That’s basically it.
First I have a template that contains a search engine. In this search engine is entered a string (ID) This string is received by another template. This works well.
On the other hand I have a function that runs a scraper within the google scholar profiles and displays the data in the terminal. This scraper receives a (url) containing the string entered in the previous browser.
The problem is that I do not know how to do that when I send the string (ID), it is received by the scraper first and then load the template where these data will be displayed.
This is the code for my project.

results.js
– (Nothing)–
I was looking at the meteor documentation but I do not quite understand. I think the most convenient thing is to create an Oncreated object from the results template. I hope someone could help me to solve this problem.
Thank you very much to all.
