escaping question mark in regex javascript

javascript regex literals

This is a simple question I think.

I am trying to search for the occurrence of a string in another string using regex in JavaScript like so:

 var content ="Hi, I like your Apartment. Could we schedule a viewing? My phone number is: ";

 var gent = new RegExp("I like your Apartment. Could we schedule a viewing? My", "g");

 if(content.search(gent) != -1){   
     alert('worked');     
 }

This doesn't work because of the ? character....I tried escaping it with \, but that doesn't work either. Is there another way to use ? literally instead of as a special character?

You need to escape it with two backslashes 

\\?
