Jquery tokeninput - Regex as a token

[siavashfdst]

Hi
I want to have a regex expression like ^([-+/]\d+(.\d+)?) for mathematical expressions as well as some texts for operands in my token lists in loopj jquery tokeninput. like this:

$(document).ready(function() {
        $("#demo-input-local").tokenInput([
            {id: 7, name: "salary"},
            {id: 11, name: "interest_rate"},
    {id: 51,  name: /^([-+/*]\d+(\.\d+)?)*/  },
        ], {
            theme: "facebook"
        });
    });

but, ^([-+/]\d+(.\d+)?) regex inside tokeninput doesn't work and this error occurs:

  Uncaught TypeError: row[$(...).data(...).propertyToSearch].toLowerCase is not a function

Can you help me?
