ember.js - component cannot find action -

i have component has text field, this

<div>     {{input type='text' insert-newline='postmessage' class="form-control" autofocus="true"}}     <input type="hidden" name="uid" value={{room.uid}}/> </div> 

the component have snippet, lives inside route called room

export default ember.route.extend({   model(params){     this.store.findrecord('room', params.uid);   } }); 

to handle action in input, created controller room: app/controllers/room.js

import ember 'ember';  export default ember.controller.extend({   actions: {     postmessage(params){       console.log(params);     }   } }); 

but when hit enter, error:

uncaught error: <chathub-ember@component:chat-room::ember1071> had no action handler for: postmessage 

i tried put action in route , didn't worked

in room.hbs file,

{{my-component myaction='postmessage'}} 

and in my-component.js

import ember 'ember';  export default ember.component.extend({   actions: {     postmessage(params) {       this.sendaction('myaction', params);     }   } })
