i set tab 1 title js file.

how solve ?

regards

you have identify tab unique id

 <tab title="tab 1"  id='tab1' icon="ks_nav_ui.png"> 

in same js file exemple index.js (the tab defined in index.xml) can use :

$.tab1.title="my title" 

if set title js file can use application events: in index file define application event listener :

ti.app.addeventlistener("app:changetabtitlle",function(e){                             $.tab1.title=e.title;                         }); 

and other js file have send tab title using fireevent:

ti.app.fireevent("app:changetabtitlle",{title:"my tab title"});
