Hi! I am working on a lightning component action to update a checkbox if the opportunity is won. The button is working fine, but there is an extra blank pop up with the alert message. I need to show just the alert message, not the blank screen. Can anyone help. Thank you!

({
 doInit : function(component,event,helper){
        $A.get("e.force:closeQuickAction").fire();
      var id = component.get("v.recordId");
      var action = component.get("c.updateOpportunity");
        action.setParams({
               "opportunityId" : id
        });
        
        action.setCallback(this, function(response) {
            if (response.getState() == "SUCCESS") {
                console.log("Save completed successfully.");
               //$A.get("e.force:closeQuickAction").fire();
                alert('Contracted!!Please refresh your screen');
             $A.get("e.force:closeQuickAction");
                  $A.get('e.force:refreshView').fire();
            }else{
                alert('Opportunity is not won!!!');
            }
             var dismissActionPanel = $A.get("e.force:closeQuickAction");
             dismissActionPanel.fire();
        });   
             $A.enqueueAction(action);
      },
     cancel : function(component, event, helper){  
     //$A.get('e.force:refreshView').fire();
      $A.get("e.force:closeQuickAction").fire();
}, 
})

Component-

<aura:component controller="generateContractClass" implements="flexipage:availableForRecordHome,force:hasRecordId,force:lightningQuickActionWithoutHeader" access="global">
    <aura:attribute name="recordId" type="String" />
    <aura:handler name="init" value="{!this}" action="{!c.doInit}"/>     
   </aura:component>

Blank pop up that I need to remove-

 

Hi! I've a javascript button that I need to move to lightning. The converter tool is not able to help.
So, there is a custom  button that marks a checkbox selected if the opportunity is won, else shows an error message.  
 
{!REQUIRESCRIPT("/soap/ajax/39.0/connection.js")}
var o = new sforce.SObject("Opportunity");
o.id = "{!Opportunity.Id}";
if ({!Opportunity.IsWon}){
o.SBQQ__Contracted__c = true;
result = sforce.connection.update([o]);
window.location.reload();
} else {
alert("This opportunity has not been marked as won.")
}

I tried converting it into lightning component, but not getting the desired functionality. 
Class-
public class generateContractClass{
@AuraEnabled

public static void updateOpportunity(string recId){
Opportunity obj ;

for(Opportunity temp : [select id,SBQQ__Contracted__c,StageName from Opportunity where id =: recId LIMIT 1]){
obj = temp;
}
Opportunity IR = new Opportunity();
IR.id = obj.Id;
if(IR.StageName == '6. Won'){
IR.SBQQ__Contracted__c = true;
}
update IR;

}
}

Component -
<aura:component controller="generateContractClass" implements="flexipage:availableForRecordHome,force:hasRecordId,force:lightningQuickAction" access="global">
<aura:handler name="init" value="{!this}" action="{!c.doInit}"/>
<lightning:spinner variant="brand" size="large"/>
</aura:component>

Controller-
({
doInit : function(component,event,helper){
var action = component.get("c.updateOpportunity");
action.setParams({
"recId": component.get("v.recordId")
});

action.setCallback(this, function(response) {
if (response.getState() == "SUCCESS") {
alert("You did it!!!!!!");
$A.get('e.force:refreshView').fire();
}else{
alert('Opportunity is not won!!!');
}
});
$A.enqueueAction(action);
},

})
