Pass params in listenAndPromise

[vivekiyer114]

support.jsx

.....
fetchData = () => {
        var params = {
            'internshipbuffer':this.state.buffer_id
        }
        supportAction.getMessage(params).then(this.updateData)
    }
.....

supportAction.jsx

import Reflux from 'reflux'
import supportResource from '../resources/supportResource'

var actions = Reflux.createActions({
    'getMessage': {
        children: ['completed', 'failed']
    }
});

actions.getMessage.listenAndPromise(supportResource.getMessage(params));

export default actions;

supportResource.jsx

import Api from '../util/api'

var supportResource = {
    getMessage(params) {
        return Api.get('/internshipbuffer/getChat', params);
    }
}

export default supportResource;

I am getting an error in supportAction.jsx :-

params is not defined

How to pass params to the resource ?
If i don't pass params i am getting undefined response
