How to initialize dynamically added input tag field?

I am using Bootstrap jquery input tag field plugin which works fine on page load.Each input tag element works ok as function has been initialized in document.ready function. Problem occurs when new input tag is added dynamically by appending to the code . If I try to re initialize the function it doubles every other tag input . Is there any way to initialize it again just for the newly added element ?
