use this to get your functions

 object["elem"]

in jQuery you could use

$(object["elem"]).each(function(index,value){
   value();
});

in native JavaScript you could use

for(var i = 0; i < object["elem"].length; i++)
{
   object["elem"][i]();
}

You just call it by using () :

var fnarray = object[name];
var i;
for (i = 0; i<fnarray.length; i++) {
  fnarray[i](); // execute the function
}

Your Exec function should be like this

function Exec(ElementName)
{
    if (object[ElementName])
    {
        for (var i = 0; i < object[ElementName].length; i++)
            object[ElementName][i]();
    }
}
Exec('elem');
