Can i in js controler set parameter to a record and then update it by force : record data?

component:

<aura:component
  implements="flexipage:availableForRecordHome,force:hasRecordId"
  controller="SimilarCasesControler"
  access="global"
>
  <aura:attribute name="simpeParentCase" type="Object"/>  
  <aura:attribute name="parentCase" type="Object"/> 
  <aura:attribute name="recordId" type="Id" />
  <aura:attribute name="similarCases" type="Object[]" />
  <aura:handler name="init" value="{!this}" action="{!c.doInit}" />
  <aura:handler
    name="sendCase"
    event="c:parametersForUpdateEvent"
    action="{!c.updateRecords}"
  />
  <force:recordData
    aura:id="caseUpdate"
    recordId="{!v.recordId}"
    mode="EDIT"            
    fields="Id,
            Origin,
            SuppliedEmail,
            Country__c"
    targetRecord="{!v.simpeParentCase}"
    targetFields = '{!v.parentCase}'
    recordUpdated="{!c.recordUpdated}"                
  />
</aura:component>

Controler:

({
     updateRecords : function(component, event, helper) {
         var caseForMerge = event.getParam("case");
         if(caseForMerge!=null){   
             component.set('v.parentCase.Country__c','Hungary');
             var smth =component.get('v.parentCase');
             console.log(JSON.parse(JSON.stringify(smth)));                                  
         }
         },
    recordUpdated : function(component, event, helper) {
        component.find('caseUpdate').reloadRecord();
    } 
})
