Fire Controller Method on Dynamically Created Component

Question

I dynamically created a preexisting component to render in a modal layered above my "parent" component. I passed in attributes and everything functions great but upon a button click in the parent component, i'd like to fire a method in the dynamically created component (as well as a method in the parent controller)

here is my code for the dynamically created component. I can add more but as this seemed more of a structure question and not a bug question i dont know if its relevant

createAComponent : function (cmp, event, helper) {
    $A.createComponent(
        "c:uploadSorter",
        {
            "aura:id": "findableAuraId",
            "policyrecordID": cmp.get("v.recordId"),
            "fileId": cmp.get("v.fileId"),
            "handleNavigate": cmp.getReference("c.handleClick")


        },

                        //"onclick": cmp.getReference("c.handlePress")
        function(newUploader, status, errorMessage){
            //Add the new button to the body array
            if (status === "SUCCESS") {
                var body = cmp.get("v.body");
                body.push(newUploader);
                cmp.set("v.body", body);
            }
            else if (status === "INCOMPLETE") {
                console.log("No response from server or client is offline.")
                // Show offline error
            }
            else if (status === "ERROR") {
                console.log("Error: " + errorMessage);
                // Show error message
            }
        }
    );

I am thinking an event handler so I am fumbling around with those but any advice would be greatly appreciated

Answer 1

Just validating that yes, you should be using an event to fire the method from the parent container.

you will still be referencing the method using cmp.getReference("c.handlePress")

and from your handlePress method, fire the event in which the parent component should have a handler.
