javascript - calling wrong method ExtJS -


i have piece of code :

listeners:  {     beforerender: function()      {         if (importbutton == true)          {             this.menu.add(             {                 text: 'import',                 iconcls: 'importicon',                 listeners:                  {                     click: new ifauthorizing('import')                 }             })         }         this.menu.add(         {             text: 'consultation',             iconcls: 'searchicon',             listeners:              {                 click: menuconsultation             }         })      } }

that supposed add items menu when conditions ok.

it's working, button added if conditions matches.

the problem coming 

listeners:  {     click: new ifauthorizing('import') }

this listener supposed appended menu item, triggered during beforerender event of parent.

function ifauthorizing(arg) {     console.log('import') }

the 'import' displayed in console logs during beforerender event, , if click on menu item supposed have click method, nothing happens.

i know why.

new ifauthorizing('import')

here operator new tries create object , interpretes ifauthorizing constructor. constructor called immediately, that's why fires on beforerender event. result object not copy of function ifauthorizing, can't called on menu item's event desired result.
