What is wrong in gulp file?

Question

gulp.js

I’m stupid today)) Guys, tell me what’s wrong, otherwise my head doesn’t understand!
Does not track changes in jade files (everything is fine with sass), although the task runs normally! Where is the error?

var gulp = require('gulp');
var sass = require('gulp-sass');
var jade = require('gulp-jade');
var sassGlob = require('gulp-sass-glob');

var path={
    sass:{
        entry:'src/styles/main.scss',
        src:'src/styles/section/*.scss',
        dist:'dist/'
    },
    jade:{
        src:'src/*.jade',
        dist:'dist/'
    }
};
gulp.task('sass', function () {
    return gulp.src(path.sass.entry)
        .pipe(sassGlob())
        .pipe(sass().on('error', sass.logError))
        .pipe(gulp.dest(path.sass.dist));
});
gulp.task('jade', function() {
    var YOUR_LOCALS = {};

    gulp.src(path.jade.src)
        .pipe(jade({
            locals: YOUR_LOCALS,
            pretty:'\t'
        }))
        .pipe(gulp.dest(path.jade.dist))
});
gulp.task('watch', function() {
    gulp.watch(path.sass.src,['sass','jade']);
});
gulp.task('default', ['sass','jade','watch']);

Answer 1

gulp.watch(path.sass.src,['sass']);
gulp.watch(path.jade.src,['jade']);
