It works fine there is prooflink
HTML:

<div id="dialog">
      <p>THIS IS DIALOG!!!</p>
    </div>

    <button id="opener">Open Dialog</button>

And Jquery:

$(function() {
    $( "#dialog" ).dialog({
      autoOpen: false
    });

    $( "#opener" ).click(function() {
      $( "#dialog" ).dialog( "open" );
    });
  });

The selector is trying to find an element with the id dialog but it looks like you don't have one. Try this:

Javascript:

$(document).ready(function ()
{
    function click()
    {
        $('#dialog').dialog({
            autoOpen: false,
            width: 250,
            height: 180,
            modal : true
        });
    }
});

HTML:

 <div id="dialog">
       Your dialog message.
    </div>

    <button type="button" id="put" onclick="click()">Insert data</button>

function click(){
       $( "#dialog" ).dialog({
        width : 250,
        height: 180,
        modal : true
        });
}

I am using jquery-2.1.0.min.js and jquery.ui-1.10.4.

Here is my full source code:

(For the jquery-ui.css link tag, change: href="path_to_your_jquery-ui/themes/base/jquery-ui.css")

(For the jquery script tag, change: src="path_to_your_jquery/jquery-2.1.0.min.js")

(For the jquery-ui script tag, change: src="path_to_your_jquery-ui/ui/jquery-ui.js")

(For your demos.css link tag, change: href="path_to_your_jquery-ui/demos/demos.css")

    <!-- this in-file styling is used to hide the #dialog element initially -->

    <script> 
      $(document).ready(function() {
        $("#put").on("click", function(evnt) {
          $(function() {
            $("#dialog").dialog({
              width:250,
              height: 180,
              modal:true
            });
          });
          evnt.preventDefault();
        });        
      });
    </script>
  </head>
  <body>
    <div id="dialog" title="Basic dialog">
      <p>
        This is the default dialog which is useful for displaying information. 
        The dialog window can be moved, resized and closed with the 'x' icon.
      </p>
    </div>
    <div>
      <button type="button" id="put">Insert data</button>
    </div>
  </body>
</html>

Be sure to pass an event parameter to your callback function in your 'on click' function and call the preventDefault() method on it. Read more about event.preventDefault() Also, here's an good read on event.preventDefault() vs. return false
