Bug: Event duplication on refresh

[ArneKlein]

When using selectpicker('refresh') the click events on the $button are always added, if the html of the select tag has been changed. This leads to a performance degradation, especially for large dropdowns.

A workaround for this bug is to destroy the selectpicker before refreshing it.

As shown in Firefox before refresh:

Refresh with the following code:
var dropdown = $('#dropdown'); dropdown.html(''); dropdown.selectpicker('refresh');

Looks like the click listener in the checkDisabled function is the source.
