Input mask compatibility with safari

[Manikandansece]

I have a blazor project with imask enabled and it is working as expected in chrome & edge browser but getting null value in safari. Any thoughts.

script:
window.contactJsFunctions = {
inputmask: function () {
var maskOptions = {
mask: '000.000.000',
lazy: false,
};
var element = document.getElementById('mobilePhone');
var mobilePhoneMask = IMask(element, maskOptions);
}
};

html:
<input type="text" id="mobilePhone" @bind-value="mobileno"/>
<button @OnClick="test"> test

code:
protected void test()
{

        if (!string.IsNullOrEmpty(mobileno))
        {
            var mob = mobileno;
            Console.WriteLine(mob);
        }
        else
        {
            Console.WriteLine("It's null");
        }
    }
