button does not work in a vaading-grid

[fwermus]

I am trying to add a button in each row inside a grid, but I could not get onclick working. Any help would be appreciated

function Messages({ newMessage }) {
  function edit(e){
    alert("testing with no luck");
  }

...

  return html`
        <vaadin-grid id="grid"  theme="row-stripes">
          <vaadin-grid-column header="Edit">
            <template>
              <vaadin-button theme="primary" @click="${e=>edit(e)}" >testing</vaadin-button>
            </template>
          </vaadin-grid-column>
        </vaadin-grid>
`
}

I also tried declaring function outside function messages and several tries
