javascript - Datepicker some problems with opening -

I use my web app in datepicker jquery, but I have a problem: two of the two tabs are my Near two menus, was I using Dedeeper in each other's menu and there is a menu in the second tab and I also use Detector. When I load my web page, and try to set some dates with the datepicker, then this is the job (it was opened at Doteppe). But after that I go to the second menu in this tab or other tab and try to set some date in my input date, but the datapicar does not open. I also use Ajax in this page. What is wrong? Thx!

Date picture ({dateFormat: "yy-mm-dd", changeMonth: true});}); & Lt; / Script & gt;    
 
 
 is a problem selector  
  $ ("#  
  The ID should be unique to a page   
 Instead of using  squares.   
 Because you are using the  ID selector , it tried to find the first example of the element. Once it is found, the search stops again, it will never apply to this element in other tabs.  
 Change  
  input type = "text "Name =" date "" id = "dateTime"   
 
  input type = "text" name = "dateTime" class = "dateTime"    P> and then select the selector  
  $ (". DateTime")    < / Html>
