Card click function in Google App Script add-on?

Question

Cannot understand why when I'm pressing the button it triggers the function multiple times. Also, the event handler handleCardClick(e) returns back whole json (instead of saying what action was triggered). Any idea on what I'm doing wrong?

function testLogic(input) {
  Logger.log("testLogic triggered" + input);
}

function buildCategoryCardV2(categories) {
  const buttons = categories.map(category => ({
    text: category,
    onClick: {
      action: {
        function: testLogic(category),
        actionMethodName: 'showCategory', 
        parameters: [{ key: 'category', value: category }]
      }
    }
  }));
  const card = {
    cardId: 'category_selector',
    card: {
      name: 'Category Selector',
      header: { title: 'Inventory Request', subtitle: 'Please select a category' },
      sections: [{ widgets: [{ buttonList: { buttons: buttons } }] }]
    }
  };
  return card;
}

Update:

This is the right syntax for the return which will tell the value of the parameter:

e.commonEventObject.parameters

And correct syntax for the function:

function buildCategoryCardV2(categories) {
  const buttons = categories.map(category => ({
    text: category,
    onClick: {
      action: {
        "function": "handleCardClick",
        "parameters": [
        // Pass the variable's value as a parameter
        { "key": "categoryPressed", "value": category } 
      ]
      }
    }
  }));
  const card = {
    cardId: 'category_selector',
    card: {
      name: 'Category Selector',
      header: { title: 'Inventory Request', subtitle: 'Please select a category' },
      sections: [{ widgets: [{ buttonList: { buttons: buttons } }] }]
    }
  };
  return card;
}
