title: bootstrap-table x-editable plugin, can't set type to select
body: <p>I'm using bootstrap-table with the x-editable plugin, which is working mostly except I am unable to change the type of the input on the x-editable popup. I've tried setting <code>data-type="select"</code> and <code>type: 'select'</code> but it always shows as type <code>text</code></p>
  
  <p>This fiddle shows the issue, the table should be using the select type but does not, the link outside of the table with the same options does work.</p>
  
  <pre><code>&lt;table id="table-hover" data-toggle="table" data-show-toggle="true" data-show-columns="true" data-url="/gh/get/response.json/wenzhixin/bootstrap-table/tree/master/docs/data/data1/"&gt;
      &lt;thead&gt;
          &lt;tr&gt;
               &lt;!-- this field doesn't show select input --&gt;
              &lt;th data-field="name" data-editable="true" data-type="select"&gt;Name&lt;/th&gt;
              &lt;th data-field="stargazers_count"&gt;Stars&lt;/th&gt;
              &lt;th data-field="forks_count"&gt;Forks&lt;/th&gt;
              &lt;th data-field="description"&gt;Description&lt;/th&gt;
          &lt;/tr&gt;
      &lt;/thead&gt;
  &lt;/table&gt;
  
  &lt;!-- works! --&gt;
  &lt;a href="#" id="fruits" data-type="select"&gt;banana&lt;/a&gt;
