fireAppEvent : function(cmp, event) {
        var appEvent = $A.get("e.c:ConversationEvent");
        var convoId = event.target.getAttribute("data-id");
        console.log(event.target);
        console.log(convoId);
        appEvent.setParams({
            "message" : convoId });
        appEvent.fire();
    },

The problem is that it uses the element that I clicked on instead of the div that I set the onclick to. By that I mean if I click on the text part of the div, the event.target is the <p> tag, if I click on the image, the event.target is the  <img> tag, but what I want is for it to always get the data from the original <div> tag. 
 

How can I go about doing this?
