I am trying to make a Lightning Component that displays some field for viewing purposes, then when a button is clicked, it reveals a different set of fields that are editable. When the user clicks to save, it should return to the view only page with the updated information that the user changed. Here is my code: (It is currently not registering onclick events)
Component:

<aura:component implements="flexipage:availableForRecordHome,force:hasRecordId">
    <aura:attribute name="recordId" type="String" />
    <aura:attribute name="record" type="Object"/>
    <aura:attribute name="simpleRecord" type="Object"/>
    <aura:attribute name="recordError" type="String"/>
    
    <force:recordData aura:id="recordEditor"
      					recordId="{!v.recordId}"
      					layoutType="FULL"
      					mode="EDIT"
      					targetRecord="{!v.record}"
      					targetFields="{!v.simpleRecord}"
      					targetError="{!v.recordError}"
      					recordUpdated="{!c.handleRecordUpdated}"
                      	fields="Id, 
                                Customer_Health__c,

Controller:

({
    handleSaveRecord: function(component, event, helper) {
        component.find("recordEditor").saveRecord($A.getCallback(function(saveResult) {
                                                                 if (saveResult.state === "SUCCESS" || saveResult.state === "DRAFT") {

    },

        	$A.util.addClass("updateHealthFields", "slds-hide");  
    },
    handleRecordUpdated: function(component, event, helper) {
        var eventParams = event.getParams();
        if(eventParams.changeType === "LOADED") {
           // record is loaded (render other component which needs record data value)
            console.log("Record is loaded successfully.");
        } else if(eventParams.changeType === "CHANGED") {
            // record is changed
        } else if(eventParams.changeType === "REMOVED") {
            // record is deleted
        } else if(eventParams.changeType === "ERROR") {
            debugger;
            // there’s an error while loading, saving, or deleting the record
            console.log(eventParams);
        }
    },
})

Currently it doesnt seem like the button is processing the onclick method.
