JSX conditional render not updating based on state change

Question

I'm creating a JSX component with StencilJS and my component isn't re-rendering based on its state change. I have no idea why:

import { Component, Prop, State } from '@stencil/core'

@Component({
  tag: "button-popover-group",
})

export class ButtonPopoverContainer{
  @State() showPopover:boolean = false;
  @Prop() popoverContent:JSX.Element;

  toggleShowPopover() {
    this.showPopover = !this.showPopover;
    console.log(this.showPopover);
  }

  render() {
    return (
      <div class="rba-something">
        <my-button onClick={this.toggleShowPopover}/>
  
        {this.showPopover ? 
          <my-popover>
            {this.popoverContent}
          </my-popover> : 
          null
        }
      </div>
      
    )
  }
}

My console log statement verifies that the state is being changed, but for some reason my popover box is never visible

Answer 1

Ok, the answer was to change the toggle function to a fat arrow function, as the binding to 'this' was getting lost in the JSX
