Folks,

I'm configuring a toast and I need to pass the controller's text to the <h2> tag of the view of the lightning component

TestAlert.cmp

<aura:component implements="flexipage:availableForRecordHome,force:hasRecordId,lightning:actionOverride,lightning:backgroundUtilityItem" access="GLOBAL" controller="AlertController">   

<aura:attribute name="Alert" type="Alert__c" default="{'sobjectType': 'Alert__c',
                         'Tipo_de_Alerta__c': '',
                         'Name': '',
                         'Alerta1__c': ''
                          }"/>
    
    
<aura:handler name="init" value="{!this}" action="{!c.doInit}"/>
    
<div class="demo-only" style="height: 4rem;">
	<div class="slds-notify_container slds-is-relative">    
		<div aura:id="alerta" role="status"> 
			<div  class="slds-notify__content">
                
<h2 class="slds-text-heading_small ">	Alert message here		</h2>
    
<lightning:buttonIcon iconName="utility:close" variant="bare" alternativeText="Close"
 iconClass="{!v.type == 'warning' ? 'light' : 'dark'}" size="small"
 class="slds-button slds-button_icon slds-notify__close slds-button_icon-inverse"
 onclick="{!c.close}"/>      
    
			</div>
		</div>
	</div>
</div>

    
</aura:component>

doInit : function(component, event, helper)
    {

          
  var tipoAlerta = component.find( "alerta" );
        
  $A.util.addClass( tipoAlerta, "slds-notify" );
  $A.util.addClass( tipoAlerta, "slds-notify_toast" );      
  $A.util.addClass( tipoAlerta, "slds-theme_success" );    


//Code to pass text to view in tag <h2> </h2>
}
