Grunt js not opening in browser on server command - gruntjs

Question

When I do a 'grunt serve' in my terminal it just sits and watches. it never opens my browser. I'm not sure what I am missing.
Take a look at this and tell me what I am doing wrong:
module.exports = function(grunt) {
// Project configuration.
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
uglify: {
options: {
banner: '/*! <%= pkg.name %> <%= grunt.template.today("yyyy-mm-dd") %> */\n'
},
build: {
src: 'src/<%= pkg.name %>.js',
dest: 'build/<%= pkg.name %>.min.js'
},
my_target: {
files: {
'js/min/main.min.js': ['js/main.js'],
'js/min/libs.min.js': ['bower_components/jquery/dist/jquery.min.js','bower_components/bootstrap/dist/js/bootstrap.min.js']
}
}
},
compass: {
dist: {
options: {
config: 'config.rb', // css_dir = 'dev/css'
sassDir: 'sass',
cssDir: 'css',
}
}
},
watch: {
all: {
files: '**/*',
options: {
livereload: true
},
}
},
connect: {
server: {
options: {
port: 8000,
hostname: 'localhost',
}
}
}
});
// Load the plugin that provides the "uglify" task.
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.loadNpmTasks('grunt-contrib-compass');
grunt.loadNpmTasks('grunt-contrib-uglify');
grunt.loadNpmTasks('grunt-contrib-connect');
grunt.loadNpmTasks('grunt-serve');
// Default task(s).
grunt.registerTask('build', ['uglify','compass']);
grunt.registerTask('server', [
'uglify',
'compass',
'watch',
'connect'
]);
};
