I want to send extra information from my handlebars script to my controller; this is my code:

<a {{action "resetState" data="state1" }}>reset1 </a>

I can't retrieve state1 in my controller; how do I send extra strings to the backend?

The API says you can pass in multiple parameters.

html and handlebars:

{{officename}} 
<button {{action "actionTest" "hello" "goodbye" officename}}>See parameters through action in the console</button>

controller:

actionTest: function(a, b, c){
   console.log(a);
   console.log(b);
   console.log(c);
},

See it in action in this jsbin

You can pass one or more context objects to the action handler by including them after the name of the action, like so:

{{action resetState state1}}

You will probably also need to specify a target (target="MyApp.someObject", or target="this") unless you want the action to go to your router. If you do want your router to get the message, you'll either need to send it a defined object and have the dynamic segment be :objectname_id to get an object out of it, or use the deserialize method.

route: '/service/:some_dynamic_segment',

    deserialize: function(router, params) {
       //params should equal {some_dynamic_segment: 'whatever you passed in'}
    }

If you do send the action to a place other than your router, keep in mind that other events are all intercepted by the view, not the controller, in case you want to keep all that stuff together.
