js:

({
    doInit : function(component, event, helper) {
        var action = component.get("c.getLabel");
        action.setCallback(this, function(response) {
            var state = response.getState();
            if (state === "SUCCESS") {
                component.set("v.mylabel", response.getReturnValue());
            }
            // error handling when state is "INCOMPLETE" or "ERROR"
         });
         $A.enqueueAction(action);
    }
})

    <aura:handler name="init" value="{!this}" action="{!c.doInit}" />
