export default connect(state => ({

Answer 1

Basically I am not giving solution on React, but it is same as any functional constructor thingy. May be use the below, in order to have a instance of you class available to you in every function/ module.

class KickIra extends Component {
    constructor(props) {
        super(props);

        this.state = {popoverIsActive: true};
        this.self = this;
        this.launchGoalDetails = this.launchGoalDetails.bind(this);
        this.hidePopover = this.hidePopover.bind(this);
        this.sportsFollow = this.sportsFollow.bind(this);
    }
   ......
   ......
 }

Then, use it to call function:

onClick={self.hidePopover}

Answer 2

In react onClick elements should be used in something like

onClick={()=>{

  }}

using the fat arrow notation does the binding thing for you and you can call the method now as this.function()
