Get LinkedIn Access Token with OAuthSimple in Javascript

This will create a phonegap linkedIn login, its just a worked around code though, but this works atleast for me

    var consumer_key = "key";
    var shared_secret = "secrete";
    self.oauth = OAuthSimple(consumer_key, shared_secret);  var linkedInScope = 'r_basicprofile r_emailaddress w_messages r_network';
    var url = self.oauth.sign({action: "GET", path: "https://api.linkedin.com/uas/oauth/requestToken", parameters: {scope: linkedInScope, oauth_callback: "oob"}}).signed_url;
    var request = 'requestToken';
    var linkedInObj = new Object;
    function linkedInWorkAround(url,request,data){
        var callType = 'GET';
        var xhr = $.ajax({
            url         : url,
            beforeSend  : function(){
                $.mobile.loading( 'show' );
                if(request == 'linkedIn_login'){
                    callType = 'POST';
                }
            },
            timeout     : 8000,
            data        : data,
            type        : callType,
            success: function(r){
                $.mobile.loading( 'hide' );
                if(request == 'requestToken'){
                    var oauthRes = r.split('&');
                    $.each(oauthRes, function(k,v){
                        var resObj = v.split('=')
                        linkedInObj[resObj[0]] = resObj[1];
                    });
                    url = 'https://www.linkedin.com/uas/oauth/authenticate?scope='+linkedInScope+'&oauth_token='+linkedInObj.oauth_token;
