why apex is not calling from controller method in developer console

Hi Developer Community, 
I was not able to find why my apex is not calling from controller method ,
can anyone please tell me the reason for this.

please check my code below 

request1 :  function(component, event, helper) {
            var recId = component.get("v.selectedId");
            alert('hi');
         //   var recordId =component.get("v.recordId");
            var action = component.get("c.fetchCompetitions");
              action.setParams({
            "recordId" : component.get("v.recordId"),
                  "recId" : recId
                             
        });
            $A.enqueueAction(action);
}

APEX code:

  @AuraEnabled
    public static void fetchCompetitions(String recordId, String recId){
                  System.debug('hi');
                   system.debug('recordId' +recordId);
                    system.debug('recId' +recId);
        List<Opportunity> opp=new List<Opportunity>();
        Opportunity o = [select id,Name,MainCompetitors__c from Opportunity where id=:recordId];
        List<Competitor__c> cmptList=[select id,Name  from Competitor__c where id=:recId];
        for(Competitor__c comp : cmptList){
           Opportunity opList = new Opportunity();    
           opList.MainCompetitors__c = comp.Name;        
            opp.add(opList);
        }
       update opp; 
        system.debug('opp' +opp);

    }

Hi Akhil,

Please try to use code like below: 
request1: function(component, event, helper) {
        var recId = component.get("v.selectedId");
        alert('hi');
        var action = component.get("c.fetchCompetitions");
        action.setParams({
            "recordId": component.get("v.recordId"),
            "recId": recId
        }); // Create a callback that is executed after 
        action.setCallback(this, function(response) {
                var state = response.getState();
                if (state === "SUCCESS") { // Alert the user with the value returned 
                    // from the server 
                    alert("From server: " + response.getReturnValue());
                    // You would typically fire a event here to trigger 
                    // client-side notification that the server-side 
                    // action is complete 
                } else if (state === "INCOMPLETE") {
                    // do something 
                } else if (state === "ERROR") {
                    var errors = response.getError();
                    if (errors) {
                        if (errors[0] && errors[0].message) {
                            console.log("Error message: " + errors[0].message);
                        }
                    } else {
                        console.log("Unknown error");
                    }
                }
                $A.enqueueAction(action);
            }
        }

Apex code can be kept as is.Also ensure you are using controller="ApexClassName" in your component definition file.

Hi akhil,

Have you add Controller attribute in <aura:Component tag to link the Apex Class like <aura:component controller="CLASSNAME">?

In case you find any other issue please mention.
