Hi Girish,

I tried with the below code and it is working as expected.

Component: 
<aura:component implements="force:appHostable"> 
    <lightning:card title="Emp Details">
     <lightning:button label="Base" title="Base action" onclick="{! c.handleClick }"/>  
    </lightning:card>
</aura:component>

Controller:
  
({
    handleClick : function(component, event, helper ) {
        alert("Show Alert");
        console.log('into console');
    }
})

If this solution helps, Please mark it as best answer.

Thanks,

Hi Girish,

How did you test this. Did you add this component as a tab? 

Thanks

I'm trying in the salesforce Developer console on chrome browser.
While being on a component tab I clicked on the controller and from there adding the onclick function.

Thank you Sai Praveen for your help
