[BUG] filterToggle not working with update from 2.0.1 to 2.2.3

[origandrew]

toggleFilter can perform initial filter but cannot toggle off.

Quick debug shows data-filter as a number and checking the this.options.filter which only contains strings. So the toggled state after a few clicks would result in checking if 1 is in array ["1", "1", "1"].

Expected Behavior:

Unexpected Behavior with latest version of Filterizr:

changing the filterizr version to 2.0.1 results in a working toggle function
