how to check check box and getting whether checkbox is checked in javascript selenium

how to check check box and getting whether checkbox is checked in javascript selenium and node. I tried using .click on the element also tried using native javascript code to do that.but nothing worked for me.

driver.findElement(webdriver.By.id('//*    
[@id="myTable"]/table/tbody/tr[1]/td[1]/input')).
then(function(element){
   element.click().then(function(){//body goes here

};

I have edited the code in SO itself so there might be braces problem.in actual code its not the braces problem.

any solutions to do so?
