Facebook Login and Sharing issue Titanium

I am integrating Facebook login and share. In login controller login functionality is working fine. But after login it is redirected to share controller in which share is implemented. . But my problem is, if a user logged in to the app without using Facebook login (direct login), he has to login to Facebook from share page . At this point login event defined in login controller is fired, and again redirects the user to share page. I don’t want to trigger the login event defined in login controller. Instead trigger the one defined in share controller itself.

login.js // controller

var fb = "";
fb = require('facebook');
fb.appid = “**********”;
fb.permissions = ["email", "public_profile"];

function loginWithFb() {

    fb.forceDialogAuth = true;
    if (Ti.Network.online) {
        if (fb.loggedIn) {
            faceBookHandler();
        } else {
            fb.authorize();
        }
    } else {
        alert('There is no Internet connection. Please retry when connectivity is restored.');
    }
}

fb.addEventListener('login', function(e) {
    if (e.success) {
        faceBookHandler()
    }
});

function faceBookHandler() { 
   $.loginWindow.close();
   Alloy.createController('share').getView().open();
}

share.js

var facebookShare = function(msg,showRequestResult){
    var fb = "";
    var fb = require('facebook');
    fb.appid = ********;
    fb.permissions = ['publish_stream'];
    fb.forceDialogAuth = true;
    if (Ti.Network.online) {
        // The activity indicator must be added to a window or view for it to appear
        if (fb.loggedIn) {
                var data = {
                Name : ‘xyxz,
                message : msg
            };
            fb.requestWithGraphPath('me/feed', data, "POST", showRequestResult);
        } else {
            fb.authorize();
        }
        } else {
        ui.showAlert('An error occurred while connecting to Facebook');
        fb = null; 
    }
};

$.shareBtn.addEventListener("click”,function(e){

    facebookShare(fbMessage,showRequestResult);         
});

function showRequestResult(e) { 
    if (e.success) { 
        alert(“posted”);
    }
}

Please help me to solve this issue
