Unable to clear tags when using multiple

[JanhaviDahihande]

I'm using autocomplete with multiple and using ('#el').html('') to clear all the tag values.
But that clears the values in the input box which is shown on the UI and not from the internal stack.

Hence, the onExist function is called when trying to enter new values after clearing.
Kindly tell us what's the right way to clear the tags list.
