Как передать данные JSON из одной функции JavaScript в другую функцию JavaScript?

JS + Jquery + Rails 4

1.) view.html.erb

<%= select_tag "schedule[id]", options_for_select(@travel_names), {:multiple => true, :onchange => "renderSchedules(#{raw @schedule_hash.to_json},#{raw @deals_hash.to_json});" } %>

@schedule_hash = экземпляр, @deals_hash = экземпляр, переходящий в js-функцию как формат json.

2.) webapp.js

function renderSchedules(json_data, deals_hash){
   new_json_data = filterSchedule(json_data, deals_hash);
   //More Code
}

function filterSchedule(json_data, deals_hash) {
//More Code
 $('#active_fiters_blk').append('<a href="#" id="active_travel_filter" style="color:#F26F21;margin-right:3%;" value="'+operator_ids[i]+'" onclick="removeTravelFilter('+json_data+','+deals_hash+')">"Link"</a>');
// Here i am getting json_data = [object Object], deal_hash = [object, Object] on console , i need to pass json data to removeTravelFilter function
}

function removeTravelFilter(jd, dh){
  //Some COnditions
  renderSchedules(jd, dh);
  // From here also i need to pass json data to renderSchedule function.
}
