VueJS select object from list and display with function

Question

I need to get the element I click which is displayed in a list. And print this element on a method which is on my vue instance throug mail-list tag which is on index.html

So I have Vue component which iterates json object and only prints two attributes from every element of it:

Vue.component('mail-list', {
  props: ['inboxmail'],
  methods: {
    selectmail: function(){
      this.$emit('selectmail', this.mail);
    }

  },
  template:
  `
  <div>
    <ul>
      <li v-for="i in inboxmail" @click="selectedmail">
      {{i.from}}:{{i.subject}}
      </li>
    </ul>
  </div>
  `
  });

After run this I have two elements displayed on my index.html which are:

• test1@test.com:Hi

• test2@test.com:How are you?

I want to click one of this two elements and get the one I clicked. Then send it to vue method called setSelectedMail throug mail-list tag which is in index.html

index.html:

<div id="app">
        <mail-list v-bind:inboxmail="inbox" @selectmail="setSelectedMail($event)"></mail-list>
</div>

And finally, heres is the vue instance from where I want to get the selected mail:

let options = {
  el: "#app",
  data: {
    inbox: '',
    selectedMail:{}
  },
  methods: {
      setSelectedMail: function(mail){
          this.selectedMail = mail;
      }

  } //end methods
 }
//ViewModel (vm)
let vm = new Vue(options);

What am I doing wrong?

Check this. some corrections in your code.

@click="selectmail(i.from)"

methods: {
        selectmail: function(value) {
          this.$emit("selectmail", value);
        }
      }
