I have created a custom button in my form view. After clicking on the button I want to generate one alert. For that I have created the following code:

odoo.define('survey_inherit.button_click',function(require){

"use strict";

console.log('In button file');

var formView = require('web.FormView');

var relationFields = require('web.relational_fields');

var core = require('web.core');

var QWeb = core.qweb;

var formButton = formView.extend({

console.log('Test');

 self.$('#button_click').click(function (e){

alert('Test');

console.log('Button event');

});

});

return {

 formButton : formButton,

};});

But it gives me below error

Uncaught SyntaxError: Unexpected token '.'

what is the problem? Error is related to code?
